Select the equation of the line that passes through the point (3, −1) and is perpendicular to the line on the graph. (20 points)
the graph is a horizontal line going through (-4 ,2.5) - (4, 2.5)
a: y = −1
b: y = 3
c: x = −1
d: x = 3

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

the equation is not included but the answer is (1.50, 2.00, 2.75)
