Ataxi cab service charges a flat fee of $8 plus an additional $1.50 per mile. show the relationship between the total cost and the number of miles driven. also, what is the independent variable, dependent variable, and eauation

Equation:  y = 1.5x + 8, where y = total cost and represents the dependent variable and x = the number of miles and represents the independent variable.  

Step-by-step explanation:

The relationship between the total cost and the number of miles driven is a linear equation.  That means that the rate of change is the same regardless of the number of miles driven.  After the initial flat fee of $8, the rate is $1.50 per mile.  So, in order to calculate the total cost of the trip, you will need to multiply the rate ($1.50) by the number of miles and then add the initial fee of $8.  In this relationship, the total cost ('y') is the dependent variable, because it is dependent on the number of miles driven.  The number of miles ('x') is independent because it is the cause of the total.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
