Question

Write an equation of a line that contains the following two points in slope intercept form

(-2,4) (3,-1)

Answer 1

y = -x + 2

Explanation:

The slope intercept form equation of this line can be written like this :

y = my + p ; where m is the slope and p is the y intercept.

`m = (-1-4)/(3-(-2)) = (-5)/(5) =-1`

then the equation becomes y = -x + p

(-2,4) is a point of the line means 4 = -(-2) + p

then p = 4 - 2 = 2

finally, y = -x + 2
