To convert the equation \(4x + y = -12\) into slope-intercept form (which is \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept), follow these steps:
-
Start with the original equation: \[ 4x + y = -12 \]
-
Subtract \(4x\) from both sides: \[ y = -4x - 12 \]
Now, the equation is in slope-intercept form.
Thus, the correct response is: y = -4x - 12 (y equals negative 4 x minus 12)
