Write an equation in standard form for a line that passes through the points (-3, 2) and (3, 6)

Respuesta :

It would be y=2/3x+4.
(-3,2) (3,6)
6-2 4 2
----- = ---- = ---
3+3 6 3

y-2=2/3(x+3)
y-2=2/3x+2
+2 +2
------------------
y=2/3x+4
-4 -4
-------------
2/3x=y-4
-y -y
-------------
2/3x-y=-4
(3) (3)
-------------
2x-y=-12
