3. determine which ordered pair is not a solution of y = –5x – 4.
a: (10, –52)
b: ( 7, –39)
c: (–7, 31)
d: (8, –44)

A

Step-by-step explanation:

Let's try choice A.

y = -5x-4

(10, -52)

-52 = -5(10)-4

-52 = -50-4

-52= -54

-52 is not equal to -54, so A is the answer.

step-by-step explanation:

first, eliminate the parenthesis:
