Find the x and y intercept of the equations.
1.5x+6y=30
2.x4y=16
3.3x+4y=12
How would I solve these and what is the anwsers

For 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 yintercept.
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 yintercepts.
In order to find xintercepts, 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 :)
