y = 7x + 2.
I am not sure what you want to find, but I assume you put the coordinates into the equation and find whether they fit.
A. (3, 15).
y = 7 * 3 - 2 = 21 - 2 = 19
y is not equal to 19, so A does not work.
B. (-1, -10).
y = 7 * -1 -2 = -7 - 2 = -9
y is not equal to -9, either, so B does not work.
C. A combination of the two coordinates, which we know do not work.
D. Neither. Neither of the coordinates work, so this is the answer.
