To find a solution to a linear equation, you really can any number you want to substitute into the equation for x or y. But since you’ll need to use that number to for the other variable it’s a good idea to choose a number that’s easy to work with.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
