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

y = −1
y = 3
x = −1
x = 3
please help :(

Answer 1

The answer is D. x = 3

Good luck on your schoolwork!

Answer 2

-- The points (0, 2.5) and (4, 2.5) are both 2.5 above the x-axis.

-- The line through them is a horizontal line. Its equation is y = 2.5 .

-- Any line perpendicular to it is a vertical line.

-- The vertical line through the point (3, -1) is the line x = 3 .
