Question

The line through (4,7) and (-2,1) slope intercept form

Answer 1

y = x + 3

Explanation:

`m=(y2-y1)/(x2-x1) = (1-7)/(-2-4) = (-6)/(-6)=1`

y - intercept can be found by using one of the two points and plugging it into the slope intercept formula (y=mx+b)

I will use (-2,1) because it is easier

y = 1

x = -2

m = 1

1 = 1(-2) + b

1 = -2 + b

1 + 2 = -2 + 2 + b

3 = b
