for 7 & 8 you use the equation
your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation

Answer: 1,250
Step-by-step explanation:
Given: The total number of students in the school= 25,000
Since each class has 10 students , therefore, the number of classes in the school=
Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day =
Also, each teacher teaches 4 classes.
Then the number of teachers in the school =
Hence, the number of teachers are at Big Big School = 1,250
