Question

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?

Answer 1

B. 42

Hope this helps!

Answer 2

Write out the governing equation:

y = kx.

Take any point from the given table. You haven't shared the table, so I will invent a point: (2, 9).

Then find k: k = 9/2 Then the equation becomes y = (9/2)x.

Now let x = 7 and find y: y = (9/2)(7) = 63/2

Answer: y = 63/2
