To rearrange the slope formula \( y = mx + b \) for \( m \), follow these steps:
-
Start with the original formula: \[ y = mx + b \]
-
Subtract \( b \) from both sides: \[ y - b = mx \]
-
Divide both sides by \( x \) (assuming \( x \neq 0 \)): \[ \frac{y - b}{x} = m \]
Thus, the rearranged formula for \( m \) is: \[ m = \frac{y - b}{x} \]
