Question

for the data in the table does y vary directly with x if it does write an equation for the direct variations x|y 2|10 4|24 6|36
- yes y=2x
-yes y= 5x***
-yes y=7x
- no, y doesn't vary directly with x

Answer 1

Your choice is incorrect, it only works for the first ordered pair.

Your ordered pairs are (2,10), (4,24), (6,36)
To be a direct variation, we must have a linear function passing through the
origin.
Yours does not, so it is not a direct variation.

Furthermore, the slope between the first 2 points = (24-10)/(4-2) = 7
the slope between the 2nd pair of points = (36-24)/(6-4) = 6
So it fails on both conditions.

Answer 2

so would it be c?
