The coordinates of point R are (-4, -3). What are the coordinates of R’ after a counterclockwise rotation of 90° about the origin?

A. (4, -3)
B. (-3, 4)
C. (3, -4)
D. (4, 3)

C. (3, -4)

Step-by-step explanation:

As harleygilman7 states: C). (3, -4) is the correct answer.

Step-by-step explanation:

I took the test and it was correct :)

throw the computer

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
