Question 153318: I need the steps for this please
Find an equation for the line with undefined slope and passing through the point (9-7)

Let's look at the formula for the slope of the line,
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
For the slope to be undefined the denominator must equal 0.
x%5B2%5D-x%5B1%5D=0
x%5B2%5D=x%5B1%5D
All x values must be the same.
Given the point, (9,-7), then the
equation is
x=9
