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.

y = −1
y = 3
x = −1
x = 3

Answer 1

Think about this, in (3, -1), which one is the x-value? Which one is the y-value? And how do you know if a line is perpendicular?
