Many of the following problems can be modeled with a linear equation. Analyze them and identify what quantities the variables x and y represent. The information provided in the problems is adequate to determine a point and a slope or two points on the line.

The slope and one point on a line are given. A coordinate of a second point is missing. Find the missing coordinate so that the second point is on the line.
