Graphing Using the Slope and Y-Intercept
How do you graph using the slope and y-intercept like in this problem 2y+4x=0?
Karin from Algebra Class Says:
In order to graph this equation, you will need to rewrite the problem in slope intercept form (y = mx + b).
So, 2y + 4x = 0
Subtract 4x from both sides:
2y +4x -4x = 0 - 4x
2y = -4x
Divide both sides by 2.
2y/2 = -4x/2
y = -2x + 0
-2 is your slope and 0 is the y intercept. Plot the y intercept on your graph and use the slope to plot your next point. Then draw a straight line through the two points.
