Answer:
d. 0.85m + 2.50
Step-by-step explanation:
In the figure attached, the complete question is shown.
We can see in the table that $2.50 is a fixed charge, that is, it is not modified by any variable. On the other hand, for each travelled mile, the cost of the travel increases $0.85 ($0.75 by mileage charge + $0.1 by city gas tax). Then, if m miles are travelled, the cost of the travel increases 0.85*m
You are given the points in which the line intercepts. Using this info, we can use these numbers to find the slope.
m = (y2-y1)/(x2-x11) = (2-4)/(2-1) = -2/1 = -2
Our end result we want is the point-slope intercept formula : y=mx+b
We are still missing b, the intercept, so pick either of the two points (it doesn't matter which) and plug them into the equation. I will use (1,4), but again you could use either.
4 = (-2)*1 + b
6 = b
So now your final equation for the line after plugging in b and m is
y = (-2)x +6
Answer:

Step-by-step explanation:
is what you are looking for.
So with x = -5, it would look like this

Simple math now.
-(-5) is 5

-5 * -4 = 20.
So it should be 
5-8=-3
-25+20-21 = -26
So the answer is
Answer:
B.
Step-by-step explanation:
We are given the function:

Which represents the population of a certain city <em>x </em>years after it was founded.
The y-intercept is the y-value when <em>x</em> = 0. So:

If <em>x </em>= 0, this means that zero years have passed since the city was founded.
So, the y-intercept represents the initial amount of people when the city was founded (in this case, there were 7870 people).
The correct answer is B.
