Slope of a Line Slope basically describes the steepness of a line Free powerpoints at
If a line goes up from left to right, then the slope has to be positive Conversely, if a line goes down from left to right, then the slope has to be negative
Definitions of Slope Slope is simply the change in the vertical distance over the change in the horizontal distance
The formula above is the one which we will use to find the slope of specific lines In order to use that formula we need to know, or be able to find 2 points on the line
If a line is in the form Ax + By = C, we can use the following formula to find the slope:
Horizontal lines have a slope of zero while vertical lines have no slope HorizontalVertical m = 0 m = no slope
Note Note to browsers This slope lesson is interactive and I have students use graph paper as they follow along This is formulated for the California High.

Goal: By the end of the lesson, students will be able to find the slope of a line from a graph.
Slope and y-intercept Lesson 8-3 p.397. Slope and y-intercepts When studying lines and their graphs (linear equations), we can notice two things about.
2-3 Slope Slope 4 indicates the steepness of a line. 4 is “the change in y over the change in x” (vertical over horizontal). 4 is the ‘m’ in y = mx + b.
Objective - To find the slope of a line. Slope -The rate of change that determines the direction of a line and how steep it is. Slope = vertical change.

SLOPE. The slope ( m ) of a line is a measure of how steep or slanted the line is. Just think of the pitch of a roof or steepness of a hill.
1.4 Linear Equations in Two Variables. Definition of Slope The slope of the line through the distinct points (x 1, y 1 ) and (x 2, y 2 ) is where x 2.

Slope and y-intercept. Lines have both slope (m) and a y-intercept (b). Slope describes the steepness of the line as well as its direction. Positive.
Objective The student will be able to: 1) write equations using slope-intercept form. 2) identify slope and y-intercept from an equation. Designed by Skip.
