It depends on what information you have. If you have the slope (m) and at least one ordered pair (x, y), then all you do is plug in the numbers and solve for b. For example:
y=mx+b
ordered pair: (3, 2)
slope: 1/2 or 0.5
2 = 0.5(3)+b
2 = 1.5 + b
0.5 = b
If you have two ordered pairs, simply calculate the slope of the line first and then plug in the numbers as above.
To calculate slope, use:
m = (y2-y1)/(x2-x1)
What else can I help you with?
How do you use the slope and y- intercept in the equation ymx b to graph the line?
If you mean: y = mx+b then it is the formula for a straight line equation whereas m is the slope and b is the y intercept
How does changing m affect the graph of an equation in the form ymx plus b?
It rotates the graph about the point (0, b). The greater the value of m, the more steeply it rises to the right.
An equation often written in ymx b?
You're talking about y=mx+b which is the standard line equation.
The equation of a line in slope intercept form is ymx plus b where m is the slope of the line?
If you mean: y = mx+b then the slope of the line is m and the y intercept is b
In the linear equation ymx b what does the b stand for?
In the equation Y=mx+b, which is what I believe you mean, 'b' is the y intercept of the graph. In other words, if the equation is plotted in standard Cartesian coordinates, the straight line crosses the y-axis at the height b above the x axis.
What is slope in ymx b?
m
Which letter represents the y-intercept in the slope-intercept equation of a line ymx b?
If you mean: y = mx+b then m is the slope and b is the y intercept.
Why cant you find ymx b to find the equation of a vertical line?
Because in a vertical line the slope is undefined, there is no "y" answer or "b" value and the line is in the form of x = some number such as x = 3 which is a vertical line.
What letter represents the y intercept in the slope intercept equation of a line ymx plus b?
If you mean y = mx+b then the slope is m and the y intercept is b
Why is the equation ymx b called the slope-intercept form?
y=m*x+b is called the slope-intercept form because it describes a line where m is the slope and b is the point on the y-axis that the line intercepts.
When you graph a line using slope intercept form do you start by graphing m or b first?
Start with b. To do this, plot the point (0, b). "Begin with B and Move with M!"
How do you do a linear graph?
A linear line is just a straight line. To graph it, you can use this equation: y=mx+b where m = the slope of the line, and b = the y-intercept of the line, in other words, where the line crosses the y-axis.
