Hello!
To find our answer, let's plug this point into the equation and find the y-intercept.
-6=-3(4)+b
-6=-12+b
b=6
As you can see, 1 has the y-intercept +6.
Therefore, our answer is
I hope this helps!

1. First, we are going to find the value of 
form April. We know form our problem that <span> the maximum afternoon temperature in month, x, with x = 0 representing January, x = 1 representing February, and so on; therefore:
January </span>
February
March
April
Now that we know that the value of that represent April is 3, we just need to replace with 3 in our model and evaluate:
We can conclude that the maximum temperature in April will be 60.
2. Remember that in a function of the form
is the amplitude
is the vertical shift
We have tow option to change our model to increase the maximum temperature to global warming:
1. Increase the value of D to increase the vertical shifting of the model. D affects the maximum value of the function; if we increase D, the maximum value of the function will increase as well. We know from our model that
, so to increase the maximum temperature of our model, we just need to increase the value of 60.
2. Increase the value of A to increase the amplitude of the model. The amplitude, also increases or decreases the maximum value of the function -regardless of the sing of A, so if we increase the value of A, we will increase the value of the function. We know from our model that
, so to increase the maximum temperature of our model, we just need to increase 30 (without considering the sign).

April
Now that we know that the value of
We can conclude that the maximum temperature in April will be 60.
