Answer:
(86.2,0) is the x-intercept.
Step-by-step explanation:
You can use the slope formula to figure this one out:
Just use two of the points on the table, any of them will work:


Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:

Now just solve for b to get the y intercept:

Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.

And that's the x-intercept.
