Answer 1

try to come up with two equations in y = mx + b form; one for the 30-people scenario and one for the 50-people scenario

since you are given neither m, nor b, you can only plug in x at this point

Answer 2

umm

Answer 3

30 = m(180) + b?

Answer 4

hm, no, x is the number of people, y is the total charge

Answer 5

(quick correction, you should be able to plug in both x and y into each equation)

Answer 6

180 = m(30) + b
220= m(50) + b

Answer 7

Those are just points

(30,180) and (50,220)

Use the formula to find the slope between two points ¯\_(ツ)_/¯

\(m=\large \frac{y_2-y_1}{x_2-x_1}\)

Answer 8

ah. I was going to suggest subtracting the two equations but that method works, too.

Answer 9

Either works ¯\_(ツ)_/¯

Whichever you feel most comfortable with

Answer 10

m = 220-180/50-30

40/20

m = 2

Answer 11

Yeah I got that too
\(y=2x+b\)

Substitute any point back into the equation to solve for b

Answer 12

any point?

Answer 13

(30,180) or (50,220)

Answer 14

180 = 2(30) + b

Answer 15

Okay, solve for b

Answer 16

120

Answer 17

Right
Our equation is
\(y=2x+120\)

Base rate means the flat fee for the bus which is basically $120

The cost for each person is $2

Answer 18

oho k

Answer 19

Yes
