Question

Graph with a line going through points zero comma two point five and four comma two point five.

Select the equation of the line that passes through the point (3, −1) and is perpendicular to the line on the graph.

A. Y= -1
B. Y= 3
C. X= -1
D. X=3

Answer 1

(0,2.5)(4,2.5)...u will notice that the y's are the same.....that means this is a horizontal line and y will always be 2.5.

so u want a perpendicular line...going through (3,-1)...a perpendicular line would be a vertical line...and a vertical line is represented by x = a number...so look at ur points (3,-1)....what number is in the x spot ? It is 3.....so ur perpendicular line is : x = 3
