Question 3
Indicate the answer choice that best completes the statement or answers the question.
The graphs of which pair of lines are perpendicular?
2
O a. 3x + 2y = 6, 2x – 3y = 7
Ob. 2x – 3y = 12, y = -
1
Oc. x + y = 1, 2y = -2x + 2
Od. y = 4x + 13, y = 7* - 13

Respuesta :

Answer:

A

Step-by-step explanation:

B is immediately wrong because 2x - 3y = 12 is not an equation with only x, so it can never be perpendicular to y = -1.

The two lines in C are the exact same line.

D does not have an x in the second line, so it can never be perpendicular with y = 4x + 13
