Answer 1

Let's go through each part step by step.

Part 1: Represent the relationship using words.

To find the correct sentence that describes the relationship between \( x \) and \( y \), we can look at the values provided in the table.

The pairs of \( (x, y) \) are:

• \( (0, 3) \)
• \( (1, 8) \)
• \( (2, 13) \)
• \( (3, 18) \)

We can notice that as \( x \) increases by 1, \( y \) increases by 5. This indicates that there is a consistent linear relationship.

Calculating the values from the equation template given:

• For \( x = 0 \): \( y = 5(0) + 3 = 3 \)
• For \( x = 1 \): \( y = 5(1) + 3 = 8 \)
• For \( x = 2 \): \( y = 5(2) + 3 = 13 \)
• For \( x = 3 \): \( y = 5(3) + 3 = 18 \)

Based on this, the correct answer is: D. The value of y is three more than the quantity five times the value of x.

Part 2: Represent the relationship using an equation.

Based on the consistent increases in \( y \) as \( x \) changes, the relationship can be written in the form: \[ y = 5x + 3 \]

Part 3: Graph the relationship.

Now we need to determine which graph represents the equation \( y = 5x + 3 \).

To help visualize, we can plot the points based on our table:

• For \( x = 0 \), \( y = 3 \), point \( (0, 3) \)
• For \( x = 1 \), \( y = 8 \), point \( (1, 8) \)
• For \( x = 2 \), \( y = 13 \), point \( (2, 13) \)
• For \( x = 3 \), \( y = 18 \), point \( (3, 18) \)

A straight line graph forms from these points since the relationship is linear. You should look for a graph that connects these points and has an upward slope.

Since there's no visual evidence provided, I recommend looking for a graph that accurately shows those points plotted in a straight line and rising steeply.

Determining if the relationship is a linear function

Since the relationship between \( x \) and \( y \) can be expressed with a linear equation and all changes in \( y \) correspond to consistent and proportional changes in \( x \), the relationship is indeed a linear function.

Thus, the summary of your p*arts is:

• Words: The value of y is three more than the quantity five times the value of x.
• Equation: \( y = 5x + 3 \)
• The relationship is a linear function.
