Question

The lines are parallel, find the slope-intercept form of the equation y₂

Answer 1

Since the lines are parallel, you know that they have the same slope, which is 2. If you look at the coordinate grid you can see that line y_{2} crosses the y-axis at (0, 1), making the y-intercept 1. Now that you know the slope is 2 and the y-intercept is 1, you can piece those into a slope-intercept equation.

y = mx + b where m is the slope and b is the y-intercept

y_{2} = 2x + 1
