Step-by-Step Solution

To determine the rate of change for the given equation 8y+2x=6-8y + 2x = 6, follow these steps:

  • Step 1: Rearrange the equation to isolate yy. Start by subtracting 2x2x from both sides:
    8y=2x+6-8y = -2x + 6.
  • Step 2: Solve for yy by dividing every term by 8-8 to get yy by itself:
    y=28x+68y = \frac{-2}{-8}x + \frac{6}{-8}.
  • Step 3: Simplify the fractions:
    y=14x34y = \frac{1}{4}x - \frac{3}{4}.

In the equation y=14x34y = \frac{1}{4}x - \frac{3}{4}, the coefficient of xx is 14\frac{1}{4}, which represents the rate of change (slope) of the line. Therefore, the rate of change is 14\frac{1}{4}.

Answer

14 \frac{1}{4}
