Example 4:
Let y = ax + b
Where, a = 4
Then,
y = 4x + b
As we have one point = (-2,3)
Replace in the equation:
3 = 4(-2) + b
3 = -8 + b
b = 3 +8
b = 11
So us stay:
y = 4x + 11
________________
Now let's to the 5 example:
Let y = ax + b
Where a = 3/2
Then,
y = 3x/2 + b
As the point is = (4, 7)
Then we will stay:
7 = 3(4)/2 + b
7 = 6 + b
b = 7 - 6
b = 1
Then we will stay:
y = 3x/2 + 1
______________
Now let's to the last example:
Let y = ax + b
Where , a = -4/3
Then we going to stay with:
y = -4x/3 + b
As the point is = (6 , -2)
Then,
-2 = -4(6)/3 + b
-2 = -8 + b
b = -2 + 8
b = 6
So follow:
y = -4x/3 + 6
I hope this helped!

Well what I would do first is divide the 900 student by the 445 teacher to get 20 students per teacher. Now I would take that 20 and multiply it by 110 teacher to get 2200 Students.
Answer= C) 2200 Students
Answer:
8 boys
Step-by-step explanation:
It's a ratio problem.
The ratio of boys to girls is 2:3
Since you know how many girls their are you plug it in
2:x
3:12
Basically you see how you get from 3 to 12 and the answer is to multiply by 4
Since it is a ratio problem you also multiply the 2 by 4
Your answer is 8 boys
