How can i figure this out and put it on the chart?

First you would have to know the first number in the set ( , ) is x. You always plot x first putting a dot on the correct line. Like in A -8 would be your x. So you would plot that and then plot y. y would be -2. so you find (-8,-2) on the grid by going up or down with x's number and going across with y's number. Next you just label.

The solution to the system of equations (-2,2)
