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:

\[
y = 5x + 3
\]
