100 POINTS! (the wrong answer gets reported)
Which ordered pair is a solution of the equation y= -7x +2
A (1,2)
B (8, -54)
C (5, -35)
D (1, -7)

Answer 1

Replace x with the x values of the choices and see if it solves to equal the y value:

Y=-7x + 2

A) (1,2)

Y = -7(1) + 2 = -7 + 2 = -5 not 2

A is wrong

B (8,-54)

Y = -7(8) + 2 = -56+ 2 = -54

This works out.

The answer is B
