<h2>a. -3</h2>
Step-by-step explanation:
Given Equation :

Which is in slope intercept form :

Where :
m = slope
b = y-intercept.
Thus , in the given Equation , the y-intercept is -3
We can split this up into 3 rectangles. 2 vertical ones (8 x 3) and one horizontal one in the middle (5 x (8 - 5)
8 x 3 = 24
24 x 2 = 48
5 x (8-5) = 5 x 3 = 15
now add 48 + 15 = 63 cm^2
7.6*10^3+2.3*10^5=7600+230000= 237600.
There are 237600 people living in Brooklyn and Staten Island.
