# Lesson 10

Calculating Slope

Let’s calculate slope from two points.

### Problem 1

For each graph, calculate the slope of the line.

### Problem 2

Match each pair of points to the slope of the line that joins them.

### Problem 3

Draw a line with the given slope through the given point. What other point lies on that line?

1. Point A, slope = $$\text-3$$
2. Point A, slope = $$\frac {\text{-}1}{4}$$
3. Point C, slope = $$\frac {\text{-}1}{2}$$
4. Point E, slope = $$\frac {\text{-}2}{3}$$

### Problem 4

Make a sketch of a linear relationship with a slope of 4 and a negative $$y$$-intercept. Show how you know the slope is 4 and write an equation for the line.

(From Unit 3, Lesson 8.)
