Question 364035: Can I get help showing me the steps on how to answer this question? (7,9);4x+y=8 Thank you
Answer by nerdybill(7384)   (Show Source):
You can put this solution on YOUR website! (7,9);4x+y=8
.
Question here is whether (7,9) is a point on the line:
4x+y=8
.
Since (x,y) = (7,9)
Plug it into the formla and check:
4x+y=8
4(7)+9=8
28+9=8
37 = 8 (false)
.
So, NO, (7,9) is NOT a solution (nor is it a point on the line)
