Find three solutions of the equation y = 7x – 5.
A. (3, –26), (–1, –12), (3, 16)
B. (–3, –26), (–12, –1), (16, 3)
C. (–3, –26), (3, 16), (1, –12)
D. (–3, –26), (–1, –12), (3, 16)****
ASAP PLEASE
I'll test (-3,-26) since that shows up on 3 out of the 4 options:
7(-3) - 5 = -21 - 5 = -26 so it can't be A
7(-12) - 5 = -84 - 5 = -89 so it can't be B
7(3) - 5 = 21 - 5 = 16 so it could be C
7(-1) - 5 = -7 - 5 = -12 so it could be D
We know that since (-1,-12) and (3,16) are solutions, the only option that contains both is D.
Therefore, option D is correct. The point (1,-12) does not work as a solution

Thanks AJ L!!!!!!!!!!!!
Haha, I'm glad you're in a hurry! The correct answer is D. (–3, –26), (–1, –12), (3, 16). And just a tip, you don't have to rush, math problems won't run away from you!
To find solutions for the equation y = 7x - 5, you need to substitute different values of x and solve for y. Let's go through each of the answer choices provided one by one:
A. (3, -26), (-1, -12), (3, 16)
To check if these points are solutions, substitute the x-values into the equation and see if you get the corresponding y-values:
For (3, -26): y = 7(3) - 5 = 21 - 5 = 16 (not -26)
For (-1, -12): y = 7(-1) - 5 = -7 - 5 = -12
For (3, 16): y = 7(3) - 5 = 21 - 5 = 16
Only (-1, -12) and (3, 16) are correct solutions.
B. (-3, -26), (-12, -1), (16, 3)
For (-3, -26): y = 7(-3) - 5 = -21 - 5 = -26
For (-12, -1): y = 7(-12) - 5 = -84 - 5 = -89 (not -1)
For (16, 3): y = 7(16) - 5 = 112 - 5 = 107 (not 3)
(-3, -26) is a correct solution.
C. (-3, -26), (3, 16), (1, -12)
For (-3, -26): y = 7(-3) - 5 = -21 - 5 = -26
For (3, 16): y = 7(3) - 5 = 21 - 5 = 16
For (1, -12): y = 7(1) - 5 = 7 - 5 = 2 (not -12)
(-3, -26) and (3, 16) are correct solutions.
D. (-3, -26), (-1, -12), (3, 16)
For (-3, -26): y = 7(-3) - 5 = -21 - 5 = -26
For (-1, -12): y = 7(-1) - 5 = -7 - 5 = -12
For (3, 16): y = 7(3) - 5 = 21 - 5 = 16
All three points (-3, -26), (-1, -12), and (3, 16) are correct solutions.
Therefore, the correct answer is choice D.
