Question

Aubrey bought a plant and planted it in a pot near a window in her house. As the plant grows, its height, in inches, can be modeled by the equation H = 5t + 12, where t is the number of months since Aubrey bought the plant. What is the Y- intercept of the equation and what is its interpretation in the context of the problem? The y-intercept of the function is which represents

Answer 1

H = 5t + 12

t= number of months

H= height of the plant

The equation is in slope-intercept form:

y=mx+b

Where:

m= slope

b= y-intercept

So, for our equation

m= 5

b= 12

The y-intercept of the equation is 12.

In the context of the problem, it is the initial height of the plant.
