MATH 120 Lecture 6: Chapter 2.2 Equations of Lines
Document Summary
Professor brendan sheehan chapter 2. 2 equations of lines. There"s a little bit more to the linear equation y = mx + b. It"s also called the slope - intercept equation. y = mx + b m: slope b: y - intercept. In this graph, the slope would be 3 and the y - intercept would be 1. Slopes can go in two different directions: positive and negative. In the graph, it is defined as a steep slope. This is a case where the slope is 0, or a horizontal line where x = 0. This is a case where there is an undefined slope, or a vertical line where y = 0. Let"s now go over the equation of slope, or m. A line goes through ( - 6, 8) and (5, 4). All we have to do is plug in the numbers that we"re given.
