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

1 answer

The slope-intercept form of a linear equation is given by:

\[ y = mx + b \]

where:

  • \( y \) is the dependent variable,
  • \( m \) is the slope,
  • \( x \) is the independent variable, and
  • \( b \) is the y-intercept.

To rearrange this equation for \( x \), we can follow these steps:

  1. Isolate the term containing \( x \): Start by subtracting \( b \) from both sides of the equation:

    \[ y - b = mx \]

  2. Solve for \( x \): Now, to isolate \( x \), divide both sides of the equation by \( m \):

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

Now we have rearranged the slope formula \( y = mx + b \) to express \( x \) in terms of \( y \), \( m \), and \( b \):

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