The Semmes Library will raise funds by selling bumpers stickers. The equation p = 2s − 20 is used to calculate the profit the library earns (p) if a certain number of bumper stickers (s) are sold. Which table has values that correspond to the equation?

The Pythagorean theorem is used to find the distance between two points. If that distance is "c", it satisfies the relation

... a² + b² = c²

where "a" and "b" are the horizontal and vertical differences between the point coordinates. Here,

... a = 7 - 3 = 4 . . . . horizontal difference

... b = 12 - 9 = 3 . . . . vertical difference

Then we have

... 4² + 3² = c² = 25

... c = √25 = 5

The length of AB is 5 units.
