SOLUTION: I need help graphing the equations. y=2x+6 y=-x-3 I figured that they cross at (-3.0) I got that the answers are x=-3 and y=0 but not sure how to graph both equations.

I need help graphing the equations.

---------------
They're 2 straight lines, so 2 points each is sufficient.
Pick values for x and find y
y = 2x+6
---------
x...y
0...6 --> (0,6)
-3..0 --> (-3,0)
Draw a line thru the 2 points.
Do the same for the other equation.
