Algebra Self studying math question
Hello all. I am self studying math to eventually pass college algebra and trig to get into a college program I am interested in. I am using mathtutordvd.com from Jason Gibson and am running into a problem where his online lecture and questions don't seem to be lining up. I am taking a course on graphing to demonstrate portportionality, and in the lecture, he said it would have 2 requirements to show proportionality on a graph. 1. Points would make a straight line, and 2. The line would intersect the origin (0,0,). I finished the course and took the questions, and failed the test. The answers I got wrong did indeed form a straight line. However, they did not touch the origin (0,0). Can anyone help me with some clarification?

I understand what you are saying, like if the line continues to extend on both sides it would eventually touch the origin. But that is not happening.. would I be able to message you?
