Describe what the vertical line test is used for.

The vertical line test is used to tell if a graph is a function or not. To pass a vertical line test, you would have to be able to draw a vertical line anywhere on the graph and two points can't be hit. Linear functions will pass the vertical line test, while a horizontal quadratic function will not.

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
