Question

solve the system by graphing
-2x=2y-4
2x-y=-5

Answer 1

So for this you're looking for the point that the graphs intersect.

Answer 2

Do you know how to graph these?

Answer 3

so graph them :)

Answer 4

make y the subject of the equation and then graph both of them and see where they intersept

Answer 5

You could graph them in a few ways... in the form they're in, easiest way is to find x and y intercepts.

To find the x int: set y=0 and solve for x.

To find the y int: set x=0 and solve for y.

Answer 6

is the answer (-1,3)?

Answer 7

yes

Answer 8

Check it yourself, by plugging that point in here:

-2x=2y-4
2x-y=-5

(-1, 3)... so plug in x=-1 and y=3. Check if the equations are still equal on both sides.
