See attached. The trick is to use similar triangles.
The x intercepts occur when you set the factors equal to 0. x+1=0 & x-6=0 gives you the x-intercepts. x+1=0 -> x=-1. x-6=0 -> x=6. Therefore, -1 & 6 are your x intercepts
Y+4=0.25(x-3) is the equation in point-slope form
The answer is B because the yintercept is -2
