1.5x+6y=-30

2.x-4y=-16

3.-3x+4y=12

How would I solve these and what is the anwsers

**Anonymous**, Monday, November 5, 2012 at 7:18pmFor all of them you have to solve for "y" on one side in y= mx+b

where m is your slope and b is the y-intercept.

1. y= -5x/6 - 5

2. y= x/4 + 4

3. y= 3x/4 + 3

From this you can see that "-5" "4" and "3" are your "b" values. Thus those are your y-intercepts.

In order to find x-intercepts, you set y=0 and solve for x.

so:

1. 0= -5x/6 - 5

2. 0= x/4 + 4

3. 0= 3x/4 + 3

Hope you can do this on your own :)
