Nathaniel purchases a one-year membership pass to an art museum. As a member, he receives a discounted entrance fee. The total c

It's a linear function with y-intercept = 12.

The slope-intercept form:

f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5

We have the equation of a line:

\boxed{f(x)=1.5x+12}

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

Substitute:

f(1)=1.5(1)+12=13.5

f(20)=1.5(20)+12=30+12=42

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

\$13.50-\$12.00=\$1.50

The total cost is $42.00 after 20 visits.

The graph shows the distance, y, that a car traveled in x hours:
vesna_86 [32]
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.

Hope this helps!
