y=3x-2 .....

so what is the answer
Answered by

Assume a straight line.
As x increases by 2 (5-7) y increases by 6 (13-19).
So try y = 3x
But, 13 - 3*5-2. So, try
y = 3x-2
it works for all the known pairs. So, fill in e and f.

sorry. You have the equation.
Plug in the given x or y value and solve for e or f.
You gotta do <u>something</u> here, dontcha?
