Question

Select the equation of the line that passes through the point (-2, 3) and is perpendicular to the line on the graph.

Answer 1

y = 0

y = -2

y = 3

y = 3x

Answer 2

Look at the line shown in the graph. What is the slope of this line? What is the slope of another line which is perpendicular to the one shown in the graph?

If you're able to identify the slope of (any) line perpendicular to the one shown in the graph, then you have the slope of the new line whose equation you are seeking.

You could use one of the following equations of straight lines:

y=mx + b

\[y-y _{0}=m*(x-x _{0} )\]

Answer 3

i think the slope is 0 because it stays in place

Answer 4

the slope is indeed zero, but I don't understand your reason "it stays in place."

Through which point does this new line pass?

From the slope (0) and the given point, can you now find the equation of the new line?

Answer 5

y - 3 = 0(x + 2)

Answer 6

y - 3 = 0

Answer 7

y = 3?

Answer 8

Right! Thanks so much for showing your work, as you have done. Good job!!

Answer 9

thanks to you too
