Answer:
y - 3 = 
(x - 1)
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (4 - 3) / (-1 - 1)
=
Point slope form:
y - y₁ = m(x - x₁)
y - 3 = (x - 1)
can be further simplify:
y - 3 = 
+ 
y - 7/2 = -1/2x

For number 1:
10.2 miles. 1/5 is the same as 0.2 so that's how it would be referred to. So the first 0.2 is $0.75 leaving us with 10 miles left. To calculate how many times we add the addition 0.2 mile charge we do 10/ 0.2 = 50. Multiply this 50 by the fare of $0.55 to get $27.50.
Add that $27.50 to the first $0.75 to get $28.25, option A.
For number 2:
Same process. 9.5 miles, first 0.2 miles is $0.75. Leaving us with 9.3 miles left. Rounding to the nearest fifth, I'm guessing that want it to be 9.2 miles. Divide 9.2 by 0.2 to get the amount of times the additional 0.2 mile charge is added, 46. Multiply 46 by the fare charge of $0.55 to get $25.30. Add the first $0.75 charge to get 26.05.
This answer is not up there so I'm going to use the actual 9.3 miles. 9.3/ 0.2 = 46.5. 46.5 * $0.55 = $25.575, call it 25.58. Add the first $0.75 to get $26.32.
Both of these aren't there but they both have $26 in them so I'd go with option B.

Answer:There are 23green marbles
Step-by-step explanation:
If Red marbles x
Green marbles 2x-5+x=37
Total is 3x-5=37
3x=37+5
X=14
Green therefore=2(14)-5=23
