Rearrange the slope formula y=mx+b for the quantity of interest m . Make sure to show each step.

1 answer

To rearrange the slope formula \(y = mx + b\) for the quantity of interest \(m\), follow these steps:

  1. Start with the original equation:

    \[ y = mx + b \]

  2. Subtract \(b\) from both sides to isolate the term containing \(m\):

    \[ y - b = mx \]

  3. Next, to solve for \(m\), divide both sides by \(x\) (assuming \(x \neq 0\)):

    \[ \frac{y - b}{x} = m \]

  4. Finally, rewrite the equation to present \(m\) clearly:

    \[ m = \frac{y - b}{x} \]

Now, \(m\) is isolated, and the rearranged formula for the slope is:

\[ m = \frac{y - b}{x} \]
