ILL GIVE BRAINLIEST.

This is a simple graph, but I want to know if I’m right. If the line goes through the origin does that automatically mean it’s positive?
And when it doesn’t go through the origin does that mean it’s automatically negative?
THANK YOU.!

Answers

Answer: This is a negative graph and it is proportional because it goes through the origin.

Step-by-step explanation:

Just beacause it goes through the origin does not mean it will be positive nor negative, if the line goes from the top left of the grid slanted down, it is negative. If the line goes from the top right of the graph slanted down, it is positive. It is proportional because it is a straight line that goes through the origin.

Answer:Under↓↓↓

Step-by-step explanation:

Ok so in this case it's a negative slope, because the line is going from left to right.

If the line was going form right to left then It would be a positive slope.
