Parallel Perpendicular

Find the equation of the line that passes through (-20, 2) and is perpendicular to the line shown in the graph.

Two lines are parallel when...

• They have one negative and one positive slope

• They have the same b-value (y-intercept)

• They have the same slope but different b-value (y-intercept)

• They have opposite reciprocal slopes
