Jessica says she doesn’t understand the Pythagorean theorem. She put numbers in for a, b, and c in the equation a2 + b2 = c2, but the equation isn’t always true. For example, when she put in a = 2, b = 3, and c = 4, she got 4 + 9 = 16, which isn’t correct. Jessica wants to know why the Pythagorean theorem isn’t working. Write an informative paragraph discussing Jessica’s conundrum. Why does the Pythagorean theorem appear not to be correct? What misunderstanding does Jessica have? Beckmann, Sybilla.

Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
