The temperature started at -65 degrees. It decreased at a constant rate of 45 degrees every hour. What is the y-intercept (b) for this situation?

The  y intercept for the given situation is y = -65

Step-by-step explanation:

Step 1 :

Given ,

The starting temperature = -65 degrees

Decrease of temperature every hour = 45 degrees

We need to find the y intercept for the situation

Step 2 :

Let x represent every hour and y represent the corresponding temperature at the hour

We can model the equation as

y = -65 - 45 x

Step 3 :

To find the y intercept we need to find the value of y when x = 0

Hence when x = 0 in the above equation, we have y = -65

The y-intercept as required for the given situation is y = -65

Step 4 :

Answer :

The required y intercept for the situation is y = -65
