Lesson 4.4 Notes (cont’d.): The Slope of a Line
Review:

The variable used to represent the slope of a line is _____.

The slope of a line tells you about the _________________ of the graph.

A line with a positive slope will ________ to the right, while a line with a negative slope will
__________ to the right.
Finding Slope from a Graph:
1. Identify 2 points on the line.
2. Start at either point. “Walk” from the one point to the other point, drawing a triangle as you go.
3. Count the number of blocks that you “walked” in each direction.
4. Write the slope of the line as the
. If the line is rising to the right, your slope should be positive.
If the line is falling to the right, your slope should be negative.
5. If possible, reduce/simplify the fraction.
Examples Find the slope of each of the following graphs.
1.
2.
3.
4.
5.
6.
Given the Slope, Find a y-Coordinate:
1. Write down the formula for slope: ________________
2. Substitute in the given values
3. Simplify/combine like terms
4. Solve the equation that remains.
Examples: Find the value of y so that the line passing through the two points has the given slope.
