Graph the equation and show your slope: -4x-2y=-6

Step 1. Let's put the equation in slope-intercept form given as y=mx+b where m is the slope and b is the y-intercept when x=0 or at point(0,b).

Step 2. Putting -4x-2y=-6 in slope-intercept form yields the following steps.

Add 2y+6 to both sides of the equation

-4x-2y%2B2y%2B6=-6%2B2y%2B6

-4x%2B6=2y

Divide 2y to both sides of the equation

-4x%2F2%2B6%2F2=2y%2F2

-2x%2B3=y

y=-2x%2B3

Step 3. ANSWER: The equation is y=-2x%2B3 where the slope m=-2 and y-intercept b=3.

Need one more point to graph the line since we have (0,3) as one point. A slope m=-2 means every move to one unit to the right yields two step downward.

So starting at (0,3) then one unit to the right means x2=0+1=1 and then two units down means y2=3-2=1. Then, the other point we can use to plot the line is (1,1). We can check if it satisfies the equation y=-2x%2B3 or

1=-2%2A1%2B3 which it does.

Here's the graph:
