Solve the system by graphing. y=2x+6y=-2x-4

The solution is (x, y) = (-2.5, 1). See the attachment for a graph.

Step-by-step explanation:

This is easily graphed using your graphing calculator, a spreadsheet, graph paper and a pencil, or an on-line graphing program. The lines are in slope-intercept form, so one point to graph can be the y-intercept.

To find x-intercepts, set y to zero and solve for x.

For the first equation, the x-intercept can be found as ...

For the second equation, the x-intercept can be found as ...

With the x- and y-intercepts of each equation, plotting the line is pretty simple. Find those points and draw a line through them. Read the solution from the graph where the lines intersect, at (-2.5, 1).
