1 answer

To find the linear equation that fits the given values in the table, we can start by examining the changes in x and y.

Given Data:

x | y
-----
3 | 14
4 | 4
5 | -6
6 | -16

Find the Differences:

To determine the slope (m), we can calculate the change in y when x changes.

  • For \( x = 3 \) to \( x = 4 \) (change in x = 1):

    • \( y \) changes from 14 to 4:
    • Change in \( y = 4 - 14 = -10 \)
  • For \( x = 4 \) to \( x = 5 \) (change in x = 1):

    • \( y \) changes from 4 to -6:
    • Change in \( y = -6 - 4 = -10 \)
  • For \( x = 5 \) to \( x = 6 \) (change in x = 1):

    • \( y \) changes from -6 to -16:
    • Change in \( y = -16 - (-6) = -10 \)

The change in \( y \) for each increase in \( x \) by 1 is consistently -10. Therefore, the slope \( m \) is -10.

Find the y-intercept:

We will use one of the points to find the y-intercept \( b \). We can use the point \( (3, 14) \) and the slope -10.

The general form of the linear equation is: \[ y = mx + b \]

Substituting \( m = -10 \) and \( (x, y) = (3, 14) \): \[ 14 = -10(3) + b \] \[ 14 = -30 + b \] \[ b = 14 + 30 \] \[ b = 44 \]

Final Equation:

Thus, the linear equation that describes the rule for the table is: \[ y = -10x + 44 \]

So in the form requested: \[ y = -10x + 44 \]

Therefore, the completed statement is:

  • \( y = -10x + 44 \)
