The correct answer is C. y = 1/2x + 7
In order to find this, we first have to look for the slope. We can do that by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 6)/(2 - -2)
m = 2/4
m = 1/2
Now we can solve using the slope intercept form and a given point.
y = mx + b
8 = 1/2(2) + b
8 = 1 + b
7 = b
Now we can put these into the equation and model as y = 1/2x + 7
