2 operations that undo each other (example: multiplication and division)

• Inverse Operations

• Slope Formula

• Direct variation formula

• Difference between an equation and an inequality

When do we use inverse operations? Choose all that apply.

• To solve equations

• To find slope

• To graph

• To find the zero of a function

When finding the zero of a linear function you must replace y with...

A zero of a linear function is the .... where the function equals zero, essentially where the line crosses the x-axis on a graph; it is found by setting the function equal to zero and solving for x

The point where a linear equation hits the x-axis is called

• x- intercept

• y- intercept
