Question

How do you solve the system `3x - y = -6` and `x + y = 2` by graphing?

Answer 1

(-1,3)

Explanation:

To solve the system `3x-y=-6` and `x+y=2` by graphing, put the equations in slope intercept form:
`3x-y=-6`
`-y=-3x-6`
`y=3x+6`
and
`x+y=2`
`y=-x+2`
Then graph the two equations on a coordinate plane. The intersection of the lines will be the solution: (-1,3)
