Slope of a Line

Today, we learned about the slope of a line, which can be thought of as the slant of the line. Slopes can be positive, negative, zero, or undefined. The slope of any line is defined as the rise over the run (how far up or down you go divided by how far left or right you have to travel.

We talked about how to find the slope of a line if you know the coordinates of any two points on the line. We also practiced finding a second point on the line if we knew one point and the slope.

Tonight's homework: 4.4 (12 - 37 all) It is fine to put up to six lines on one grid, provided you use different colors for each line.
