Which is not a solution to the equation 4x-y=5?

A.

(-6, - 29)

B.

(-2, - 13)

C.

(0, - 5)

D.

(9, 41)

Make y=4x-5, put x into it

y1=-24-5=-29

y2=-8-5=-13

y3=-5

y4=36-5=31

d

4x - y = 5

(4x - y) + y = 5 + y

4x = y + 5

4x - 5 = (y + 5) - 5

4x - 5 = y

Now that we have formed an easy equation, all we need to do is substitute the answers:

When x = - 6

4 (-6) - 5 = y

-24 - 5 = y

Y = - 29

(-6, - 29)

When x = - 2

4 (-2) - 5 = y

-8 - 5 = y

Y = - 13

(-2, - 13)

When x = 0

4 (0) - 5 = y

0 - 5 = y

Y = - 5

(0, - 5)

When x = 9

4 (9) - 5 = y

36 - 5 = y

Y = 31

(9, 31)

The last answer is the only one that doesn't have the same coordinates as above. The answer is D. (9, 41)
