Slope of a Line Slope basically describes the steepness of a line Free powerpoints at http://www.worldofteaching.comhttp://www.worldofteaching.com
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
Objective - To find the slope of a line.
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.

Finding the Slope of a Line From Two Points
Re-Writing Equations Part of end of class.
Laws of Exponents Whenever we have variables which contain exponents and have equal bases, we can do certain mathematical operations to them. Those operations.

Brett Solberg Sarah Schneider Ralph Davis. Students will be able to derive an accurate formula for finding the slope of a line.
EXAMPLE 2 Find a negative slope Find the slope of the line shown. m = y 2 – y 1 x 2 – x 1 Let (x 1, y 1 ) = (3, 5) and (x 2, y 2 ) = (6, –1). –1 – 5 6.
Distance, Midpoint, & Slope. The Distance Formula Find the distance between (-3, 2) and (4, 1) x 1 = -3, x 2 = 4, y 1 = 2, y 2 = 1 d = Example:
A) A(3,4), B(7,8) P(5,6). b) A(-5,-2), B(3,7) P(-1,2.5)
