The unit rate would be the slope, which is given in the equation as 18.25

To find if the given point would be on the graph, replace x with the x value of the point, solve the equation and see if it equals the Y value of the point:

Equation: y = 18.25x

Point: (8,146)

Solve: y = 18.25(8) = 146

This equals the y value of the given point, so this would be on the graph.

1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5

Answer:

239 students and 153 non-students attended to the school production of "Our Town"

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets of the school production sold = 392

Student ticket cost = US$ 3

Non-students ticket cost = US$ 5

Total collected = US$ 1,482

2. How many students and how many non-students attended?

For answering the question we will use the following equation:

x = Number of students that attended the school production

392 - x = Number of non-students that attended the school production

3x + (392 - x) * 5 = 1,482

3x + 1,960 - 5x = 1,482

-2x = 1.482 - 1,960

-2x = - 478

x = -478/-2

x = 239 ⇒ 392 - 239 = 153
