Make two equations from the information. Then graph them and see where they intersect. The answer is 62 miles. Plug 62 back into both equations and they should both be the same number.
X axes are supposed to be positive and the y is negative.
The slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
We know:
Slope (m) is -4
y-intercept (b) is -1
All you need to do is plug these numbers into the slope intercept formula given above!
y = -4x - 1
Hope this helped!
