Question

Graph the inequality y > 3/4x –1/2 using the graphing tool.

Which is a solution to the system?
(-2,-5)
(-1,7)
(1,-7)
(-5,-5)

Answer 1

You could graph the inequality.

You could also just test the points given in the options.

Answer 2

For example: (-2,-5). Note that x = -2 and y = -5.

y > 3/4x –1/2

-5 > (3/4) * (-2) - 1/2 ? Yes or No. If Yes, then the point is a solution. If no, then the point is not a solution.

Then, you move on to test point (-1,7) in the same way.
