Pick three x values, say 0,1,2
figure the y for those three values of x
plot those three points on a graph.
Connect with a line.
graph the line
3x-4y=-8
Could you show how you got the answer so I can work it out also

You can graph the line by solving for y:
-4y = -3x -8
y = 3/4x + 2
(divided everything by -4)
If x = 0 you should get 2 for y
if x = 4 you should get 3 + 2 = 5 for y
Now, you have two points (0,2) and (4,5) You always should have one more point to be sure your line is correct.
Try x = 8 (3/4)(8) = 6 then add 2
-4y = -3x -8
y = 3/4x + 2
(divided everything by -4)
If x = 0 you should get 2 for y
if x = 4 you should get 3 + 2 = 5 for y
Now, you have two points (0,2) and (4,5) You always should have one more point to be sure your line is correct.
Try x = 8 (3/4)(8) = 6 then add 2
These are the two points that I have. I'm trying to figure out a third one but its hard for me.
(-8,8)
(4,-5)
(-8,8)
