Which is a solution to the equation y = 2x – 5? A. (2, 1) B. (1, –3) C. (3, 11) D. (5, –5)

OpenStudy (cgreenwade2000):

I'm about 95% sure we just did this question.

OpenStudy (texaschic101):

hi y = 2x - 5 (1,-3) -3 = 2(1) - 5 -3 = 2 - 5 -3 = -3 (correct)

OpenStudy (anonymous):

So it's (1,-3)?

OpenStudy (texaschic101):

yep...just plug in your values (x,y) and see which one satisfies your equation

anyone?

OpenStudy (texaschic101):

give me a second and I will come up with the answer...hold on

OpenStudy (texaschic101):

4x - y = 5 (-6,-29) 4(-6) - (-29) = 5 -24 + 29 = 5 5 = 5 (correct, so not the right answer) (-2,-13) 4(-2) - (-13) = 5 -8 + 13 = 5 5 = 5 (not the right answer) (0,-5) 4(0) - (-5) = 5 5 = 5 (not the right answer) (9,41) 4(9) - 41 = 5 36 - 41 = 5 -5 = 5 (BINGO...here is your answer)
