from the looks of things I am in good company when it comes to having problems solving algebra equations. I hope you can help with this one I have been working on for two days and still don't understand.
I need ordered pairs for y=5x8 and the y intercept. my pairs are (4,0) (3,0)which may be wrong. Can you help?

Ordered pairs are pairs of values of x and y that satisfy a given equation or a function. It is presented in the order x,y and eclosed in parentheses, as in (x,y).
For the equation y=5x8, the value of x=0 gives the value of y=8, so (0,8) is an ordered pair.
This ordered pair happens to be the yintercept, i.e. the point where the line intersects the yaxis, characterized by x=0.
To get other (arbitrary) ordered pairs, substitute different values of x into the equation, and put the pair of x and y values in parentheses.
