Answer 1

To find the equation that models the linear relationship given the table of values, we can first determine the slope (\(m\)) and the y-intercept (\(b\)) of the linear equation in slope-intercept form, which is \(y = mx + b\).

Given the points from the table:

- (-2, -7)
- (0, -3)
- (2, 1)
- (4, 5)

1. **Calculate the slope (\(m\))**:

Using the formula:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

We can choose any two points. Let’s use (0, -3) and (2, 1):
\[
m = \frac{1 - (-3)}{2 - 0} = \frac{1 + 3}{2} = \frac{4}{2} = 2
\]

2. **Determine the y-intercept (\(b\))**:

Using the slope and one of the points (we can use (0, -3)):
\[
y = mx + b \implies -3 = 2(0) + b \implies b = -3
\]

3. **Equation of the line**:

Now that we have \(m = 2\) and \(b = -3\), we can write the equation:
\[
y = 2x - 3
\]

Thus, the equation that models this relationship in slope-intercept form is:

**y = 2x − 3**

So the correct response is:
**y = 2x − 3**
