Rearrange the slope formula y = mx + b for the quantitative interest m show all steps

1 answer

To rearrange the slope-intercept form of a linear equation \(y = mx + b\) to solve for the slope \(m\), follow these steps:

  1. Start with the original equation: \[ y = mx + b \]

  2. Isolate the term containing \(m\): Subtract \(b\) from both sides: \[ y - b = mx \]

  3. Solve for \(m\): Divide both sides by \(x\) (assuming \(x \neq 0\)): \[ m = \frac{y - b}{x} \]

Now, we have successfully rearranged the slope formula to express \(m\) in terms of \(y\), \(b\), and \(x\): \[ m = \frac{y - b}{x} \]
