Question 147913: Graph this equation below using the indicated method.
y = -2/3x + 4
Answer by mangopeeler07(462)   (Show Source):
You can put this solution on YOUR website! Start with an empty graph.  is already in y=mx+b form. b is where you start on the y axis with your line, in this case 4. plot one point on (0,4). -2/3 is the slope. This is also known as rise over run. -2 is the change of the y axis, and 3 is the change on the x axis. It can also be that 2 is the change on the y axis and -3 is the change on the x axis. It doesn't matter, same line.
To plot the line, just start at (0,4), the point you've already plotted, and move in one of these two directions:
--to the right 3 and down 2 (over and over to plot points) or
--to the left 3 and up 2 (over and over to plot points)
When you are done, your graph should look like this:

Equation  describes a sloping line. For any
equation ax+by+c = 0, slope is  .- X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 12/2 = 6.
- Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 12/3 = 4.
- Slope is -2/3 = -0.666666666666667.
- Equation in slope-intercept form: y=-0.666666666666667*x+4.
