Answer:Hopefully you feel comfortable with what a number line is. A graph is two number lines (called the x axis and the y axis) which cross each other at zero. A linear equation is a relationship between the two number lines. So if I gave you the linear equation “y=x”, this means if you pick a number on the x axis, the equation tells you what the number is on the y axis. So if you picked x=10, then you would know y=10. You can then draw a point at the co-ordinate (10,10), the point is there to tell you that the equation is true at that point. You can then pick another x, say x=9, then you know y=9 and you can put a point at (9,9), so you know the equation is true at that point also. You can do this with any number that you pick for x, and if you did that for every number, all the points you draw would turn into a line.
