Answer:
y = -2x + 7
Explanation:
we know that y = mx + b
we also know that plugging both of these points into this equation will work. we can create a system of two equations that will let us solve for m and b.
equation 1:
7 = m(0) + b
equation 2:
17 = m(-5) + b
based on equation 1, b = 7. put this in equation 2
17 = m(-5) + 7
m = -2
thus the equation will be
y = -2x + 7
