So, first step is to find the y=mx+b equation.
First we find the slope. Slope is equal to change in y divided by change in x.
3 - -2 = 3 + 2 = 5 = 1
4 - -6 = 4 + 6 = 10 = 2
So our slope is 1/2, or .5 y=.5x+b
Now we plug a point in to our new equation to find B.
-6 = .5*-2 + b
-6 = -1 + b
b = -5
So, D is wrong because the y-intercept is -5 ^_^ Hope I helped!
