Answer:
(-35,0)
Step-by-step explanation:
To find the x-intercept, you first have to find the slope. To do this you find change in y over change in x. So that would look like:
[tex]\frac{-51-(-68)}{-68-(-79)}[/tex]
Which would result in:
[tex]\frac{17}{11}[/tex]
That means that every time you rise 17, you go right 11.
If you then taks the highest point, (-57,-34) you can rise 17 twice to get to a y-coordinate of zero, so that means you have to go right 22, making the x-intercept
(-35,0)
