Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac.

Front

Define a reciprocal in mathematics.

Back

A reciprocal of a number x is 1/x.

Front

What is the slope formula?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation.

Front

What does it mean for a slope to be undefined?

Back

An undefined slope occurs when a line is vertical, meaning the change in x is zero.
