**Write an equation that represents the data in the table.**

Question 8.

Answer:

Compare the x- and y-values to find a pattern

Each y-value is 7 times the corresponding x-value

Use the pattern to write an equation expressing y in terms of x

y = 7x

y = 7x Final solution

y = 7x

Question 9.

Answer:

Compare the x- and y-values to find a pattern.

Each y-value is l2more than the corresponding x-value.

Use the pattern to write an equation expressing y in terms of x.

y = x + 12

y = x + 12 Final solution

y = x + 12

Question 3.

Man had 5 library books. He checked 1 additional book out every week without returning any books. Which equation describes the number of books he has, y, after x weeks?

(A) y = 5x

(B) y = 5 – x

(C) y = 1 + 5x

(D) y = 5 + x

Answer:

(D) y = 5 + x

Explanation:

He had 5 books which increased at the rate of 1 book per week so he had y = x + 5 books in x weeks

Option D

Question 4.

Stewart is playing a video game. He earns the same number of points for each prize he captures. He earned 1,200 points for 6 prizes, 2,000 points for 10 prizes, and 2,600 points for 13 prizes. Which is the dependent variable in the situation?

(A) the number of prizes captured

(B) the number of points earned

(C) the number of hours

(D) the number of prizes available

Answer:

(B) the number of points earned

Explanation:

The number of points earned depends on the number of prizes captured, therefore the number of points earned is the dependent variable.

Option B.

Question 5.

Dwayne graphed the equation y = 10 + x. Which point does the graph not pass through?

(Â) (0, 10)

(B) (3, 13)

(C) (8, 2)

(D) (5, 15)

Answer:

(C) (8, 2)

Explanation:

We notice that through the point (8, 2) the graph does not pass.

Really if we substitute 8 for r in the equation, we get:

y = 10 + 8 = 18 ≠ 2

So, the conclusion is that correct answer is C

(C) (8, 2)

Question 6.

Amy gets paid by the hour. Her little sister helps. As shown below, Amy gives her sister part of her earnings. Which equation represents Amy’s pay when her sister’s pay is $13?

(A) y = \(\frac{13}{5}\)

(B) 13 = \(\frac{x}{5}\)

(C) 5y = 13

(D) 13 = 5x

Answer:

First, we need to find an equation which describes this situation:

so, we get the following equation

y = \(\frac{1}{5}\)x

Now, we will substitute 13 for y in previous equation and we wilL find the equation which represent Amy’s pay

13 = \(\frac{x}{5}\)x

So, correct answer is B.

Question 7.

Betty earns $7.50 per hour at a part-time job. Let x be the number of hours and y be the amount she earns. Betty makes a graph to show how x and y are related. If she earns $60, how many hours did she work?

Answer:

According to informations in this task, we get the following equation which describes the relationship between hours and the amount Betty earns:

y = 7.50x

Now, we will graph previous equation:

Now, we wilt substitute 60 for y in the previous equation and calculate x on that way, which represent how many

hours she worked.

60 = 7.50x

x = 8

Betty worked 8 hours.
