Pls i need this to be right no mistakes

5 step by step equation

Slope is y = mx + b where m is the slope and b is the y intercept

So the two points are (-9, -2) and (1, 3)

m = y₂ - y₁ / x₂ - x₁ = 3 - (-2) / 1 - (-9) = 5 / 10 = 1/2

I don't remember how to find the y intercept so I used a calc. The y intercept is 5/2 

So the equation would be y = 1/2x + 5/2 which is C
