To solve the equation of a line given by \( y = mx + b \) for \( x \) in terms of \( y \), follow these steps:
-
Start with the equation: \[ y = mx + b \]
-
Subtract \( b \) from both sides: \[ y - b = mx \]
-
Divide both sides by \( m \) to solve for \( x \): \[ x = \frac{y - b}{m} \]
Thus, the correct response is: \[ x = \frac{y - b}{m} \]
