Answer 1

y+2=1/2(x-8) or y+4=1/2(x-4)

Explanation:

Okay, so point slope form is y-y1=m(x-x1). So you substitute y1 with -2 or 8 and x1 with 8 or 4.

Slope is (-2-(-4))/(8-4), which is 2/4, or 1/2. Plug that into m.

Answer 2

y+2 = 1/2(x-8)

Explanation:

We need to find the slope

m = (y2-y1)/(x2-x1)

= (-4--2)/(4-8)

= (-4+2)/(-4)

= -2/-4

= 1/2

We know the slope and we know a point, so we can use point slope form

y-y1 = m(x-x1)

y--2 = 1/2(x-8)

y+2 = 1/2(x-8)

If we had used the other point

y--4 = 1/2(x-4)

y+4 = 1/2(x-4)
