y = 72

Select all the expressions that will include a remainder.

If a line is defined by the equation y = 5x + 2, what is the slope?

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.
