Front

What is the relationship between the slopes of two lines that are PERPENDICULAR?

Back

The slopes of two perpendicular lines are negative reciprocals of each other.

Back

The y-intercept is the value of y when x = 0, represented by b in the equation.

Front

How can you determine if a point (x, y) is a solution to a linear equation?

Back

Substitute the x and y values into the equation. If the equation holds true, then (x, y) is a solution.

Front

What does the term 'system of equations' refer to?

Back

A system of equations is a set of two or more equations with the same variables.
