Answer:
C
Step-by-step explanation:
25 (2c-1)
(25 x 2c) - (25 x 1)
50c - 25
Multiples:7,14,21,28,35,42,49,56,63,70,77,84,91,98,105,112,119,126,133,140,147,154,161,168
Factors: 1, 7
walk = 9/30 - bike = 3/30 - car = 6/30 - bus = 12/30
y=5x is not linear
option A is not linear
A line can be expressed as
y=mx+b, where m=slope and b=y intercept
We are given m=6 and b=-5 so we can just use them in the equation.
y=6x-5
So C is the correct answer.
