Question

Is y=2x + 3 proportional or non-proportional

is y=5x proportional or non-proportional

Answer 1

the first is not question proportional, the second question is proportional

Explanation:

if you graph 2x+3 you can't graph it so, therefore number 1 is not proportional.

The second one is proportional because you can easily graph 5x. Therefore number 1 is not proportional, number two is proportional.

Answer 2

y=2x+3 is non-proportional. y=5x is proportional.

Explanation:

y=2x+3 is not proportional because there is the +3. also, when it is graphed on a graph, the line does not pass through the origin/zero.

y=5x is proportional because it does not have any other values attached to the y value. when it is graphed, the lie goes through the origin/zero.
