Write the equation of the line that passes through the points (4,5) and (-1,-5) in slope-intercept form.

Answer 1

(4,5) and (-1,-5) have a line through them

set slope = slope

(5+5)/(4+1) =(y-5)/(x-4)

10/5= 2 =(y-5)/(x-4)

y -5 = 2x- 8

y =2x -8 + 5 = 2x-3

y = 2x-3 is the equation in slope intercept form. slope=2 intercept = -3
