Question

Lynn is tracking the progress of her plants growth. Today the plant is 5 cm high. The plant grows on average 1.5 cm per day. Write a linear equation that represents the height of the plant after d days?

Answer 1

Answer:35cm

Explanation:

h=1.5d+5

h=1.5(20)55=35cm

Answer 2

Answer:
`y=1.5d+5`

Explanation:

The equation of the line in Slope-Intercept form is:

`y=mx+b`

Where "m" is the slope of the line and "b" is the y-intercept.

According to the information given in the exercise, you know that:

1. The height of Lynn's plant today is 5 centimeters.

Then, you can determine that that is the y-intercept. So:

`b=5`

2. Lynn's plant grows on average 1.5 centimeters per day.

You can notice that that growth is constant, which means that this will be the slope of the line. Then:

`m=1.5`

Finally, you get that the linear equation that represents the height of Lynnn's plant after "d" days, written in Slope-Intercept form, is the following:

`y=1.5d+5`
