Which equation represents the amount a left after t trips on a pre-paid $25 subway card if the price per trip is $1.75? A) t = 1.75a - 25
B) a = 1.75t + 25
C) a = -1.75t + 25

C- a=-1.75t + 25

Step-by-step explanation:

Used process of elimination

Option A makes no sense, because it uses the answer in the equation

Option B makes no sense because you would be adding, and come up with more money than you started with

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
