Answer 4

try it yourself..
find the gradient... (y2-y1) / (x2-x1)

Answer 5

i would if i could

Answer 7

Find the slope first.
m = (y2 - y1) / (x2 - x1)
I'll do (13 - 1) / (4 + 2)
12 / 6 = 2
Either way when you subtract it, m = 2.

Well now you can just substitute what you already have into the point slope form equation, which is
y - y1 = m (x-x1)
You can use either point, but you'll still get your answer as
y - 1 = 2 ( x + 2)
