Question

For 3 and 4, find the slope of the line that passes through the given points.

3. (0, 10) and (24, 6)
4. (0, 6) and (20, 14).
5. The graph shows the number of centimeters a particular plant grows over time.
a. What is the slope of the line?
b. Apply Math Models What does the slope mean?

Answer 1

Answer: 4. -1/6, 5. 2/5

Explanation:

1. The formula for slope is rise/run. To find the slope, you subtract the y coordinates (it doesnt matter the order, and you divide it by the difference of the x coordinates.

2. The y coordinates for 3 are 10 and 6, and the x coordinates are 0 and 24.

10-6/0-24 is 4/-24 which is -1/6.

3. you do the same thing for #4. The y coordinates are 6 and 14, and the x coordinates are 0 and 20. 14-6/20-0=slope. 8/20 is the slope, and that is equal to 2/5.

4. the slope for 3 is -1/6 and the slope for 4 is 2/5.
