Question

2. Which ordered pair is a solution of the equation y =

-11x + 4? Make sure you show work!
a. (0,-7)
b. (-1,-7)
c. (1, -7)
d. (2,26)

Answer 1

c. (1, -7).

Explanation:

Substitute the given values to see which set fits:

y = -11x + 4

Try (0, -7):

-11(0) + 4 = 4 . Not this one as we are looking for the result -7.

Try (-1, -7):

-11(-1) + 4 = 11+4 = 15. Not this one as we are looking for the result -7.

Try (1, -7):

-11(1) + 4 = -11+4 = -7. This is correct.
