How do you calculate the perimeter of a rectangle?

Back

P = 2(l + w), where l is the length and w is the width.

Front

What is the slope formula between two points (x₁, y₁) and (x₂, y₂)?

Back

m = (y₂ - y₁) / (x₂ - x₁).

Front

What does it mean for a point to be a solution to an equation?

Back

A point (x, y) is a solution if it satisfies the equation when x and y are substituted.

Front

How do you evaluate a polynomial expression?
