Which ordered pair is a solution of the equation? y=-2x-5

Choose 1

(Choice A)
Only (1,7)

(Choice B)
Only (2,-7)

(Choice C)
Both (1,7) and (2,-7)

(Choice D)
Neither

Step-by-step explanation:

Test these possible answers one by one.  To do this, take the x coordinate and substitute it for x in y = -2x - 5.  Determine whether the resulting y value matches or does not match the given y-coordinate.

Choice A:  x = 1.  Substituting 1 for x in y = -2x - 5, we get y = -7.  This is not the same as the given y-coordinate, 7 , so (1, 7) is NOT a solution.

Choice B:  x = 2.  Subbing 2 for x in y = -2x - 5, we get y = - 9.  No, (2, -7) is NOT a solution.

Choice C:  Please provide the coordinates.  

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
