First let's find the slope of the line through the points and


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%283--8%29%2F%281-1%29 Plug in y%5B2%5D=3, y%5B1%5D=-8, x%5B2%5D=1, and x%5B1%5D=1


m=%2811%29%2F%281-1%29 Subtract -8 from 3 to get 11


m=%2811%29%2F%280%29 Subtract 1 from 1 to get 0


Remember, you cannot divide by zero. So this means that the slope is undefined.


Since the slope is undefined, this means that the equation of the line through the points and is x=1.
