Question

(HURRY!!!)

What is the slope of a line that is perpendicular to the line shown on the graph?

A)-2
B)-1/2
C)1/2
D)2

Answer 1

(0,1)(-1,-1)
slope = (1+1)/(0+1) = 2
perpendicular lines, slope is opposite and reciprocal
so slope = -1/2

answer
B)-1/2

Answer 2

slope of perpendicular line =
`-(1)/(2)`

Explanation:

Find the slope of a line that is perpendicular to the line shown on the graph

To find slope of the given line , we pick two points from the graph

(0,1) and (1,3)

`slope = (y_2-y_1)/(x_2-x_1) =(3-1)/(1-0) = 2`

Slope of given line = 2

slope of perpendicular line = negative reciprocal of slope of given line

slope of perpendicular line =
`-(1)/(2)`
