Chapter 3 - Parallel and Perpendicular Lines - 3-8 Slopes of Parallel and Perpendicular Lines - Practice and Problem-Solving Exercises - Page 201: 11

$$y-3 = -2(x-0)$$

Work Step by Step

We know that if the slopes of two lines are the same, then they are parallel. Thus, we use the slope of the original line and plug in the second point: $$y_2-y_1=m(x_2-x_1)$$ $$y-3 = -2(x-0)$$
