How do you graph the equation y= -1/2x-3?

Question

I'm really bad at algebra2 and I have a test tomorrow morning :[

Answer 1

Let's break it down a little more, although Emily's answer is correct.
Remember the slope intercept formula?
y=mx+b

So, when x = 0, y in this case would be a -3. this is the point on the y axis where your point would be [(0, -3) when
x=0, y=-3] it crosses the y axis. How do we know? because y = -1/2x-3. When x = 0, which is the only time the line can cross the y axis, then y = -1/2 (0) -3. Thus, When x = 0, y = -3.

m is your slope Y2-Y1/X2-X1. Here the slope is -1/2. Thus for every one point you go down on the y axis, you go 2 points over on the x axis-here to the right.

Go to "purple math" or Google, "slope intercept form", or "linear equations" and you'll find lots of sites that go through this concept much better that I did, but I hope it helps.
Stay calm and rely on your knowledge, study hard and you will do well on that test.

Answer 2

Since the y-intercept is -3, plot a point at (0, -3). From there, either go right 1 down 2, or left 1 up 2 for about 3 or 4 times since the slope is -1/2 and you want a lot of points. Then just connect the dots.

Answer 3

Well, first off, the y-intercept is -3. Because of this, you will start your graph at -3. The rate of change in this equation is -1/2. So from -3, you will decrease by 1/2 each time the x-values increase. Hope this helped.

Answer 4

Plot the x-intercept (6, 0) Plot the y-intercept (0, ?3) Draw a line by using the two factors count form up a million and outstanding 2 from the y-intercept if u are asking which one doesnt belong it could be the final

Answer 5

first, start at the origin.

next count down 3 boxes and make a dot on the point (0,-3)
[thats how to graph the y-intercept]

now to make a second point, count up one box and 2 to the left and make a point at (-2,-2)
[thats how you graph the slope]

then take a ruler and connect the two points you made extending it a little bit and draw arrows on each side of the line showing that it continues forever and you have your graph =)

Answer 6

-3 is your b, or y intercept
so you start at point (0,-3).
Then your slope, is -1/2, so you go down one, to the right 2. Down one, to the right two.
