Having trouble with this problem!

**Reiny**, Sunday, December 1, 2013 at 9:51pmOnce again, the same kind of question as before.

step1: find slope

(you did that correctly and got m = -2)

step2:

use y-y1 = m(x-x1) , where (x1, y1) is either of the given points

using (2,4)

y-4 = -2(x-2)

y-4 = -2x + 4

standard form has both x and y terms on the left, the constant on the right.

so....

2x + y = 8

(using (3,2) has to give you the same equation, try it.)

I usually use the point not used to sub in my equation, to see if it satisfies the equation.

It does!

**Tina**, Sunday, December 1, 2013 at 10:07pmLet me see if I remember this... I believe you plug in one of the points into the point slope formula

y-y1=m(x-x1)

(2,4) x1=2 and y1=4 m=slope in this case -2

I hope this help
