Solve the system of equation by graphing.

Question

3x-y=4

2x+y=-4

 

___ (Type an order pair)

Answer 1

3x-y = 4

2x+y = -4

 

Put the equations into slope-intercept form:

 

y = 3x-4

y = -2x-4

 

Graph the two lines.  The point where they cross is the solution.  If you're clever, the solution can be seen by just looking at the equations (HINT: look at the y-intercepts).
