We’re always considering distance when travel. We are looking for the shortest distance but we are restricted by roads or whatever form of transportation we choose to use. The shortest distance between any two point is, however, a straight line. Given two points we look at the formula for finding the shortest distance between two point, or the distance formula.

The length of a line is not necessarily a practical value as a line goes on for ever. The length of a line is infinite. However, the length of a line segment is of more value and is a finite value. Any time we measure how long a package is or how long our table is, we are taking the length of a line segment. Learn the formula for finding the length of a line segment when given two points in either 2 dimensions or in 3 dimensions.
What does it mean for points to be equidistant? We take a look at the meaning of this and then look at how we can determine if points are equidistant using mathematics and formulas we have seen such as the distance formula.
Given two points it may be necessary to find the midpoint of the line between the two points. Learn about the midpoint formula for finding the midpoint of a line segment.
Learn what collinear points are. Practice finding and determining if sets of points are indeed collinear.
Learn what the x-intercept of a function is. Practice locating the x-intercept.
Two lines on the Cartesian plane are either parallel or intersecting. If lines are intersecting, we want to find where they cross or their point of intersection.
