Answer 1

To analyze the relationship between the values of $x$ and $y$ provided in the table, we first need to identify a pattern in the data.

Given values:

• When $x=0$, $y=3$
• When $x=1$, $y=8$
• When $x=2$, $y=13$
• When $x=3$, $y=18$

Part 1: Representing the relationship using words

From observing the values, we notice that $y$ increases by 5 each time $x$ increases by 1. Therefore, we can infer that $y$ is a linear function of $x$.

Let's analyze the options:

A. The value of y is ten less than the quantity nine times the value of x.
B. The value of y is the square of the quantity one plus the value of x.
C. The value of y is the cube of the quantity seven minus the value of x.
D. The value of y is three more than the quantity five times the value of x.
E. The value of y is ten less than the square of the quantity ten times the value of x.
F. The value of y is six times the value of x.

We can deduce that option D fits our observation best:

• The relationship can be expressed as: $y=5x+3$ (which we can verify by substituting the values).
• Thus, the correct answer is: D. The value of y is three more than the quantity five times the value of x.

Part 2: Representing the relationship using an equation

We can establish the relationship in equation form derived from our observation:

$$y=5x+3$$

This is a linear equation since it can be expressed in the form $y=mx+b$, where $m$ is the slope (which is 5) and $b$ is the y-intercept (which is 3).

Conclusion

• The relationship is a linear function.
• The equation representing the relationship is:

$$y=5x+3$$
