Question

The graph shows the number of centimeters a particular plant grows over time. Given the points​ (0,0) and ​(5​,8​), how many centimeters does the plant grow per​ week?

can someone help me with this problem please?

Answer 1

8 cm

m = -------------- This is the desired rate of change, the amount the plant

5 wk grows per 1 week.

Explanation:

Moving from point (0, 0) to point (5, 8), we see that the x-coordinate (the 'run') increases by 5 wk and the y-coordinate (the 'rise') increases by 8 cm. Thus we have the rate of change

8 cm

m = -------------- This is the desired rate of change, the amount the plant

5 wk grows per 1 week.
