Question

1. Lines m and n are perpendicular. If the slope of line m is zero, then what is the slope of line n? If you were to sketchlines m and n, what type of lines would you sketch?2. On a graph, create your own set of perpendicular lines similar to lines m and n. Choose two points on each line andprove through the slope formula, that the lines are perpendicular to each other.

Answer 1

when lines are perpendicular to each other, they make 90 degrees to each other

whenever you have a slope of 0, it means the y-axis remains constant while the x-axis increases

since m has a slope of zero, that's why it's in that position while n increases

slope = y2 - y1 / x2 - x1
