To write the equation \( 3y = 6x - 18 \) in slope-intercept form, which is \( y = mx + b \) (where \( m \) is the slope and \( b \) is the y-intercept), follow these steps:
-
Divide both sides by 3 to solve for \( y \): \[ y = \frac{6x - 18}{3} \]
-
Simplify the right side: \[ y = \frac{6x}{3} - \frac{18}{3} \] \[ y = 2x - 6 \]
So, the equation in slope-intercept form is: \[ y = 2x - 6 \]
Here, the slope \( m = 2 \) and the y-intercept \( b = -6 \).
