Complete the equation of the line through (4,-8) (8,5)

Answer 1

To find the equation of a line through two points, you first need to find the slope.

(y2-y1)/(x₂-x₁)

5-(-8)/8-4

13/4

y+8 = (13/4)(x-4) <-- this would be the equation in point slope form.

To get this equation in slope intercept form, you would first have to multiply 13/4 out and then subtract the 8 and you will get a y = equation.

Hope this helped!
