Since the inverse of a function is it's reflection over the line x=y, which has a slope of 1. The only way a function can be It'a own inverse is if it is a liner function whose slope is perpendicular to the line. Since a perpendicular line is any line with the negative recoprocal of the slope, any linear function whose slope is -1 will be it's own inverse. - stefanie math 7-12 teacher
2. Parallel lines have the same slope.
Negative 0.2
It is also zero as parallel lines have the same slope
x = -3 represents a vertical line whose slope is undefined.

Slope of a line = m slope of perpendicular line = -1/m
2. Parallel lines have the same slope.
Negative 0.2

Get the slope of the given line, by putting it into slope-intercept form. Then you can divide minus one by this slope, to get the slope of any perpendicular line.
The slope is 5 over 2, if they're paralell they have the same slope
If you dont have slope then you cant tell
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
The slope is 5. Parallel lines always have the same slope.
For example, if the slope at a certain point is 1.5, you can draw a line that goes through the specified point, with that slope. The line would represent the slope at that point. If you want to graph the slope at ALL POINTS, take the derivative of the function, and graph the derivative. The derivative shows the slope of a function at all points.
x = -3 represents a vertical line whose slope is undefined.
