Answer: The slope of a line parallel to 4x - 2y = -12 is (m=6), or just 6.
Step-by-step explanation:
In order to find the slope of the equation, we must first change the equation from standard form into slope-intercept form.
First things first is to subtract 4x from both side so that the y and slope are not on the same side of the equation, and so that the slope and y-intercept are on the same side of the equation.
4x - 2y = -12
-4x -4x
-2y = -4x - 12
Subtracting 4x from both sides of the equation successfully transforms the equation from standard form into slope-intercept form and gives you the equation -2y = -4x - 12.
The next step is to make sure that the y is positive. It is also necessary to ensure that there is no coefficient. The way to do that is to divide all terms on both sides of the equation by -2.
-2y = -4x - 12
-2
y = 4x + 6
Dividing both sides of the equation by -2 correctly and fully transforms the equation into the slope-intercept form and as well gives us the equation y = 4x + 6. From this equation we can see that the slope of the equation is 6, or (m=6).
Since the slopes of all parallel lines are exactly the same, we can conclude that the slope of a line parallel to 4x - 2y = -12 (y = 4x + 6) is 6.
