A line parallel to another line with an undefined slope must also have an undefined slope?

Sounds reasonable. If the lines are parallel, then their slopes are equal.

What is true about the slope of parallel lines?
The slopes will be the same. It is also possible that both parallel lines have no slope defined - if they are vertical.
Write an equation in slope intercept form for the line parallel to y equals -3 and with a y intercept of 7?
The line 'Y = - 3' has a slope of zero. Any line parallel to it also has a slope of zero. The line parallel to it with a Y-intercept of 7 is: Y = 7
How many ways can you prove that two lines are parallel?
Two lines are parallel if they never cross one another. Another way to tell if they are parallel is if they have the same slope. Also, if the same line intersects both of them at a 90 degree angle, they would be parallel (in other words, if both lines are perpendicular to a common line, they are paraellel).
Find the slope of a line parallel to the graph of y 4x 2?
y = 4x + 2 Find the slope of a line parallel to the given equation. First, let's take a look at what it means to be parallel. The easiest way to look at it, is to think of railroad tracks. Parallel lines are the same distance apart for EVERY point on the line. This means, parallel lines will NEVER, ever cross. There will never be a point in common with both. Now think about how this will help us with our slope in the equation. Try to answer the following. Our parallel line will have: a) the same slope as the given line OR b) a different slope as the given line That's right, (a). If you're asked to find the equation/slope of a parallel line to a given line, the parallel line will always have the exact SAME slope as your given line! Since our given line y= 4x +2 has a slope of 4, the parallel line to y = 4x +2 will also have a slope of 4. Remember, the general form of a linear equation is y = mx +b, where m = slope and b = y-intercept.
What does it mean when a math problem is undefined?
When a math problem's answer is "undefined", that means that it's an impossible answer, such as 3/0. A number can't be divided by zero because 3/0, as a word problem, would be, "How many times does zero go into three?" Since there is no real answer, they just call it undefined. Note that it can only happen with division problems, and not multiplication, addition or subtraction problems, since 3*0 is 0, 3+0 is 3 and 3-0 is 3. An undefined answer can also be in linear equations, if the line is flat (horizontal), then the slope is 0, or undefined. Simplified answer: if any number is divided by zero, it is undefined, even 0/0. In equations with slopes and lines (linear equations), if a line is horizontal, it's slope is undefined.
What is the slope of a line parallel to a vertical line?
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
What is the slope of a parallel line?
Parallel lines have the same slope. So if you have a line with slope = 2, for example, and another line is parallel to the first line, it will also have slope = 2.
If the slope of a line is 13 what is the slope of a line parallel to it?
Parallel lines have the same slope. The slope of the second line is also 13.
What is the slope of a line parallel to a line whose slope is 0?
It is also zero as parallel lines have the same slope
If the slope of a line is zero What is the slope of the line that is parallel to it?
The parallel line would also have a slope of zero (both are horizontal lines).
If two lines are parallel and one has a slope of -7 what is the slope of the other line?
If they are parallel then the slope of the other line is also 7
What is true about the slope of parallel lines?
The slopes will be the same. It is also possible that both parallel lines have no slope defined - if they are vertical.
What is the slope of all lines parallel to the x-axis?
the x-axis is the horizontal line which means the slope is 0. any line parallel also has a slope of zero
What is the slope of a line parallel to this one 4x-2y-3?
If you mean: 4x-2y = -3 then the slope of the line parallel to it will also have a slope of 2 but with a different y intercept
How is it determined whether the lines passing through some specified points are parallel perpendicular or neither?
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
How do you graph x equals 2 and what is its slope?
x=2 means that on a graph, on the x axis, there is a point. Also, since it is just x=2 it means that the slope is undefined, or that there is a line that is going through that point that is perpendicular to the x-axis. So basically there is a line that goes through (2,0) that is parallel to the y-axis.
Find the slope parallel to x y 20?
Parallel lines have the same slope. So if you have y=x+20 for example, the slope is 1 and any parallel line has slope 1 also. I think your equation is x=y+20 but since the+ and - don't show up i am not sure If it is we can rewrite it as -y=-x+20 or y=x-20 and slope is still 1 so any parallel line has slope 1.
