1. slope of AB = 4/-2 = -2

so slope of new line = +1/2

new line:
y-6 = (1/2)(x-7)
expand and doctor it up any way you want.

2. So I continued working where you left off and got y=0.5x+2.5 is that correct? or is it y=0.5x-2.5? I am pretty sure that it is the first one but I just wanna make sure.

3. y - 6 = .5x - 3.5
y = .5x - 3.6 + 6
y = .5x + 2.5
