Question

Which of the following does not represent the equation: y=2x

Answer 1

G

Explanation:

G does not match it because when we substitute the x-values from the table into the equation it doesn't make the equation true. For example, if we substitute the x value, 2, into the equation y=2x then we get

y=2x

y= 2(2)

y=4

This makes y=4 and according to the table, y should equal 2 when x is 2, not 4.

Answer 2

The answers is g because if you subtract the x and t values in the table for G, the slope is 1
