Answer:

m=3/2

Step-by-step explanation:

the line: y=mx+b

This line passes through the points

-> These points (x,y) are on the line

(-5/2,1) : x=-5/2  y=1

1=-5/2m+b                      

(-1/2,4) : x=-1/2    y=4

4=-1/2m+b

We have a system of equation:

1=-5/2m+b

4=-1/2m+b

After solving this, we have m=3/2   b=19/4

-> The slope is 3/2

Answer:

78

Step-by-step explanation:

for the right side we can just do 14*2 since there are two people per seat and 14 rows

14 *2 is 28

for the left side we just do 14*3 since there are three people per seat and 14 rows

14*3 is 42

Then we have to add the 8 students that can fit in the very back seat

42 + 28 + 8

28 + 8 is 36

42 + 36 = 78
