Question

The temperature t in fish haven Idaho starts at 20 degrees Fahrenheit at midnight when h=0. The temperature. drops 2 degrees every hour. what equation represents the temperature in T at hours H

hint: the rate of change or slope -2 degrees every o=hour. because the temperature is falling.

Answer 1

As the hint stated, the slope is -2 degrees.

So, the easiest way to make a equation is to use slope intercept.

Y=mx+b

M is the slope, and B is the Y-intercept.

so.

Y = (-2)x+20

Y = -2x+20

Answer 2

`T=-2h+20`

Explanation:

the temperature t in fish starts at 20 degrees Fahrenheit at midnight when h=0.

So when h=0 the T=20 degree (0,20)

The equation of temperature is

`T=m(H)+b`

Where m is the slope and b is the y intercept

y intercept is the initial degree , so b=20

m is the rate of change that is slope =-2

m=-2, b=20 ,
`T=m(H)+b`

The equation becomes

`T=-2h+20`
