Please help ! (Explain whether each following example is proportional or non-proportional. Please state whether it is proportional or non-proportional AND explain how you know. You will not get full credit for correct answers without an explanation.)

⦁ Is this equation proportional or non-proportional? How do you know?
equation: y = 7x -3

⦁ Is the graph below proportional or non-proportional? How do you know? (look at the attachment for the graph btw.)

I think this is not proportional.

Step-by-step explanation:

If the graph of a courting is a line or a ray thru the origin, then it's far proportional. If it's far a line or ray that doesn't go thru the origin, then it isn't always proportional.

Or if you dont understand that,

if the line passes through (0,0) that means it is proportional

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
