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

(0,2.5)(4,2.5)...u will notice that the y's are the samethat 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 3so ur perpendicular line is : x = 3

Hmmm i had this before , give me a sec
