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
