Question 173798: Please help with this problem: Which function has the ordered pair (4,4) as a solution? (A) y= 4x + 3, (B) y= -4x + 3, (C) y= 3x - 8 or
(D) y= 4 - 10
Answer by vleith(2983)   (Show Source):
You can put this solution on YOUR website! The answer is C
To get that yourself, all you need to do is plug in the the values from the given point (4,4) into each of the possible answers. Then solve. When you find the one that results in a 'true' answer, then you are home free.
So for 1)
y = 4x +3
The given point is (4,4). So the x coordinate is 4 and the y is also 4
try
4 = 4*4 + 3
4 = 16+3
4 = 19
4 does not equal 19, so answer A is not the correct one
Now do the same process for the other 3
You'll see that C ends up as 4 = 4, which is true.
