Question 694550: Question 1; Write the equations of two lines who's graphs are perpendicular to one another.
Question 2; on a map, Sandusky st. Passes through coordinates( 2,-1) and (4,8). Pennsylvania ave. intersects Sandusky st. And passes through coordinates (1,3) and (6,2) are these streets perpendicular explain?

Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
Perpendicular lines have negative inverse/reciprocal slopes.
Take a slope of 2, the negative inverse will be
A simple answer for two lines are
and , such that the first equation is a horizontal line through y=2 and the second equation is a vertical line through x =
...
Given the points (2,-1) and (4,8), the slope is
With the points (1, 3) and (6, 2), the slope is
No, these streets are not perpendicular, becuase their slopes are not negative inverses.
