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

Back

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

Front

What does it mean for two lines to be parallel in terms of their slopes?

Back

Two lines are parallel if they have the same slope.
