Answer
We used the y-intercept and the slope to graph this equation.
Work Step by Step
Our equation given to us is:
2y+4x=0
First solve for y. In order to that subtract 4x from both sides and then divide by to both sides. You get:
y=-2x
Now since our y-intercept is an implied 0, we start at the origin (0,0). Then since our slope is -2/1, go down 2 units and right 1 unit and plot the next point there. Continue doing this until you have a sufficient amount of points that can create a line.
