Step-by-step explanation:
boys is 18
girls is 24
total = 18+ 24= 42
Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
The answer to the question before the comma is -24
