Is this line proportional? If not, why? If yes, what is the constant?
Evaluate responses using AI:
OFF
Answer explanation
The line goes through (0,0), so it might be.
Find 2 points. I choose (1,4) and (-1, -4).
The constant is y over x, or y/x. So, using one set of coordinates, if this is a constant it would be 4/1, or 4.
I used that 4 to see if it works with the other set of coordinates.
-1 * -4=4
Yes, it worked with the other set coordinates.

Is this line proportional? If not, why? If yes, what is the constant?
Evaluate responses using AI:
OFF
Answer explanation
The line goes through (0,0), so it might be.
Find 2 points. I choose (1,2) and (2, 4).
The constant is y over x, or y/x. So, using one set of coordinates, if this is a constant it would be 2/1, or 2.
I used that 4 to see if it works with the other set of coordinates.
2 * 2=4
Yes, it worked with the other set coordinates.
