3x-4y=-8

**JJ**, Monday, February 18, 2013 at 5:24pmThere a few ways to do this problem.

You could chose values for x and then solve for y.

If x = 0, you would have -4y = -8 so y = 2

You need 3 points to graph the line.

Try x = 4 and then find y.

another way is to put the equation into the form of y = mx + b

-4y = -3x - 8

y = 3/4 x + 2

You can choose values for x... like 0, 4, 8 which will make the math a little easier and then find y.

**Kim**, Monday, February 18, 2013 at 5:46pmI understand the values for x but I don't understand how do you get the value for y. Could you show me the work so I can know for myself how to do it
