The table represents a linear relationship.

x −4 0 4
y −3 −2 −1

Which equation represents the table?
y equals one fourth times x minus 2
y equals negative one fourth times x plus 4
y = 4x − 2
y = −4x + 3

1 answer

To determine which equation represents the linear relationship in the table provided, we can first find the slope (m) and y-intercept (b) using the values from the table.

The points from the table are:

  1. (-4, -3)
  2. (0, -2)
  3. (4, -1)

We can use the first two points to calculate the slope \( m \):

\[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - (-3)}{0 - (-4)} = \frac{-2 + 3}{0 + 4} = \frac{1}{4} \]

Now, we can use the slope and one of the points to find the y-intercept (b). Using the point (0, -2):

Using the slope-intercept form of the line \( y = mx + b \):

\[ -2 = \frac{1}{4}(0) + b \implies b = -2 \]

Therefore, the equation in slope-intercept form is:

\[ y = \frac{1}{4}x - 2 \]

This matches the first equation:

y = \frac{1}{4}x - 2.

So, the correct answer is:

y equals one fourth times x minus 2.
