The table shown represents a linear relationship.

x 0 1 2 3
y −6 −3 0 3

Based on the table, what is the equation of the linear relationship in slope-intercept form?
y = −3x + 2
y = −3x − 2
y = 3x + 6
y = 3x − 6

1 answer

To determine the equation of the linear relationship represented in the table, we can first calculate the slope (m) using the points provided.

We have the following points from the table:

  • (0, -6)
  • (1, -3)
  • (2, 0)
  • (3, 3)

To find the slope (m), we can use the formula:

\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Using the points (0, -6) and (1, -3):

\[ m = \frac{-3 - (-6)}{1 - 0} = \frac{-3 + 6}{1} = \frac{3}{1} = 3 \]

Now that we have the slope (m = 3), we can use point-slope form to find the equation of the line. We can use one of the points, for example, (0, -6). The equation in point-slope form is:

\[ y - y_1 = m(x - x_1) \]

Substituting \(m\) and the point (0, -6):

\[ y - (-6) = 3(x - 0) \]

This simplifies to:

\[ y + 6 = 3x \]

Subtracting 6 from both sides gives us:

\[ y = 3x - 6 \]

In slope-intercept form (y = mx + b), the equation is:

\[ y = 3x - 6 \]

Thus, the correct equation of the linear relationship is:

\[ \boxed{y = 3x - 6} \]
