It's a linear function with y-intercept = 12.
The slope-intercept form:

Let's read the coordinates of two points on the graph:
(2, 15) and (4, 18)
Substitute to the formula of a slope:

We have the equation of a line:

We need calculate the value of function for x = 1 and x = 20.
Substitute:


$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

The total cost is $42.00 after 20 visits.
<h3>Answer D.</h3>
Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)
Now, we know,
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55
Here m represents the slope of graph which is nothing but rate of change of distance.
In short, option A will be your answer.

Dinos really are awesome
Hope it helps u.... .....
Step-by-step explanation:
substitute a with 2 and b with 3
2x+3
because it's the same equation it should just be an equal sign.
