For the following straight line equation, state what is the rate of change?
−8y+2x=6
To determine the rate of change for the given equation −8y+2x=6, follow these steps:
- Step 1: Rearrange the equation to isolate y. Start by subtracting 2x from both sides:
−8y=−2x+6.
- Step 2: Solve for y by dividing every term by −8 to get y by itself:
y=−8−2x+−86.
- Step 3: Simplify the fractions:
y=41x−43.
In the equation y=41x−43, the coefficient of x is 41, which represents the rate of change (slope) of the line. Therefore, the rate of change is 41.
