Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used. match each equation with its y-intercept.

To solve this problem you must apply the proccedure shown below:
 To match each equation with its y-intercept x must be zero, so you have:
 x=0 and solve for y, as following:

 1) cx+by=a  (0,a/b)
 y=a/b
 2) bx+ay=c  (0,c/a)
 y=c/a
 3) ax+by=c  (0,c/b)
 y=c/b
 4) cx+ay=b  (0,b/a)
 y=b/a
 

-1

Step-by-step explanation:

So you have -2y=2 divide by -2 both sides  and then if you divide 2 by -2 you will get -1 so that is the answer of y.

Hope that answers ur question
