There are two cell phone plans for texting. Each one's plan can be modeled with an equation where x represents the number of texts over your limit, and y is the total price.
Plan A: y = 0.25x + 17 Plan B: y = 0.15x + 25
Plan B is cheaper BY HOW MUCH if you go 100 texts over your limit?
$2.00

If you draw a circle on a graph, is it a function? why or why not?
Not a function because it doesn't pass the vertical line test.
