When Elijah left his house in the morning, his cell phone battery was partially
charged. The charge remaining in Elijah's battery, as a percentage, can be modeled by
the equation B = 27 – 4.5t, where t is the number of hours since Elijah left his
house. What is the slope of the equation and what is its interpretation in the context
nf the problem?

Answer:

The slope is -4.5

The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.

Step-by-step explanation:

In the equation y = mx + b, m is the slope.

The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.

In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.

So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
