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
