To rearrange the formula \( y = mx + b \) to solve for \( m \), we need to isolate \( m \) on one side of the equation.
Starting with:
\[ y = mx + b \]
- Subtract \( b \) from both sides:
\[ y - b = mx \]
- Now, divide both sides by \( x \):
\[ \frac{y - b}{x} = m \]
Thus, the rearranged formula for \( m \) is:
\[ m = \frac{y - b}{x} \]
From the provided options, the correct response is:
m = y − bx
(Note: There seems to be an inconsistency in the answer choices as the correct answer from the rearrangement does not appear verbatim. The structure hints that the closest match needs a correction. The correct answer should look like \( m = \frac{y - b}{x} \).)
