Question

A line passes through (-2,-2) and (2,3). Write the equation of the line in point-slope form.

Answer 1

y +2 = 5/4(x+2)

Explanation:

First we find the slope

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

= (3- -2)/(2 - -2)

= (3+2)/(2+2)

= 5/4

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

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

y +2 = 5/4(x+2)
