To find the height of the plant at different months, we can substitute the values of \( x \) (the number of months) into the equation \( y = 7 + 2x \).
-
For \( x = 1 \): \[ y = 7 + 2(1) = 7 + 2 = 9 , \text{cm} \]
-
For \( x = 4 \): \[ y = 7 + 2(4) = 7 + 8 = 15 , \text{cm} \]
-
For \( x = 10 \): \[ y = 7 + 2(10) = 7 + 20 = 27 , \text{cm} \]
Now we can fill in the table:
| Time in months (x) | Height in cm (y) | |---------------------|-------------------| | 1 | 9 | | 4 | 15 | | 10 | 27 |
So, the heights of the plant after 1, 4, and 10 months are 9 cm, 15 cm, and 27 cm, respectively.
