Question 994759: I am trying to help my grand daughter with 8th grade math. It's not the math that I learned. So can you simplify how to get the answers that she needs and understand how we got the correct answer? Example: y = x -4, on a graph and write out the answer.
Thank you!

============
y = x-4 has no unique answer.
There are an infinite # of "answers."

If you graph it, it's a straight, and every point on the line is a solution.
