Question

The lines are parallel. Find the slope-intercept form of the equation y₂.

Answer 1

Since the lines are parallel and you know the slope of $y_{1}$ is -2, you know the slope of line $y_{2}$ will also be -2. You can see on the coordinate grid that line $y_{2}$ crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get $y_{2}$ = -2x - 1.
