Answer:
The equation would be y - 9 = 17(x + 7)
Step-by-step explanation:
In order to find the equation of this line, we have to use the slope formula to find the slope.
m (slope) = (y2 - y1)/(x2 - x1)
m = (9 - -8)/(-7 - -8)
m = (9 + 8)/(-7 + 8)
m = 17/1
m = 17
Now that we have that, we can use it along with the second point to put into the point-slope equation.
y - y1 = m(x - x1)
y - 9 = 17(x - -7)
y - 9 = 17(x + 7)
