Parallel = has same slope
On points( 3,4) (-2,2)
(2-4)/(-2-3) = -2/-5 = 2/5 slope
Use same formula: (y2-y1)/(x2-x1)
Find the slope of the other points:
(-2,-5) and (-7,-3)
(-3-(-5))/(-7-(-2)) = 2/-5 = -2/5
(-1, 1) and (-6, -1)
(-1-1)/(-6-(-1)) = -2/-5 = 2/5
(0,0) and (2,5)
(5-0)/(2-0) = 5/2
(1,0) and (6,2)
(2-0)/(6-1) = 2/5
(3,0) and (8,2)
(2-0)/(8-3) = 2/5
Which has same slope of 2/5?
You can see :)

Answer:
8.5
Step-by-step explanation:
(4.08/48)×100 = 8.5
We know that pupils are students
Students = S
boys = B
Teachers = T
So....
S = 8T
Boys = 3G
T = B - 70
Since there is 8x students than teachers, I did Boys = 6x and girls = 2x
I'm going to use this next: S = 8T
8x = 8(B -70)
8x = 8(6x - 70)
8x = 4x - 560
x = 14
We know there is 8x students, so there are 112 students and we know that there is 1/8 of teachers, so there are 14 teachers.
Answer = 126.
