Question

Which ordered pair is a solution of the equation 2x− y = 9?

A)(-4,1)
B)(-2,5)
C)(5,1)
D)(6,-3)

Answer 1

y=2x-9......any point that lies on this line is a solution


im sure you meant to include a list of options...i'll tell you how to do it though....you take those points and plug the x and y values into the equation and see if you get the same thing on both sides...if you do then it is a solution...if not then its not

if its just giving a possible solution...pick a random x value and find the corresponding y value...for example

when x = 0
2(0) - y = 9
0-y = 9
y=-9

the point (0,-9) is a solution
