Question

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

Answer 1

Since you know the slope of line
`y_(1)` is 2 and that the lines are parallel, you can find the slope of
`y_(2)` by flipping the slope upside down and making it negative (-
`(1)/(2)`. You can see on the coordinate grid that
`y_(2)` crosses the y-axis at 1. When you piece these facts together into slope-intercept form, it becomes
`y_(2)` = -
`(1)/(2)`x + 1.
