Question

The table shows the height of a plant as it grows a. What equation in slope-intercept form gives the plant's height at any time?

Time Height
(Weeks)|(Inches)
2 | 12
4. | 17
6. | 22
8. | 27

y = (5/2)x + 7
y=(5/2)x +12
y=(5)x + 7
y=(5)x+12

Answer 1

Its y=(5)x+7. If the plant grows lets say 5 inches per week that would be your rate of change. Then if you look at 2/12 in order to get to 1 you have to subrtact 5 from 12 and you will get 7 so therefor your answer is y=(5)x+7
