Step 1) make a blank xy axis Step 2) label each axis with tick marks and numbers Step 3) Each row in the table you are given represents one point. For example, the first row with "Marek" will represent the point (70,70). The second row represents the point (63,63), and so on. Plot all of these points on the same coordinate axis system. Make sure you provide enough room, and scale things properly, so all points show up.
Yes, but the thing is, I don't know how to make a blank xy axis on geogebra.com. I tried using the site but its way to confusing for me.
Oh wait. I just figured it out. I'll now use the steps you provided me with to make the scatter plot. Thank you!
are you using the desktop downloaded version? or web version?
I just downloaded the desktop version like, two minutes ago.
ok you can adjust the window so you can see all of the points
click the "options" button at the top then go to "advanced"
oh wait, no that's the wrong spot
right click any blank whitespace on the graph then go to "graphics"
do you see where it says xmin, xmax, etc?
Give me a sec
Okay, yeah I see it
make sure that xmin is smaller than 0, say -10 or something that way the y axis will show up make xmax larger than the largest x value (add 10 to the largest value to get xmax)
make ymin = -10 ymax = (largest y value) + 10
now plot each point
in the input bar, you can type in each point and hit enter
Okay, do I exit the preferences window now?
yes once you have the proper window set up
Okay, now what is the input bar? Is it the bar that allows you to select point, line, perpendicular line etc?
Another question, how can I add a grid to the graph?
for me, it's down at the bottom. Do you see a blank bar like that?
Oh. Yeah, I see the bar.
Adding a grid right click any blank whitespace go to "graphics" go to the "grid" section click "show grid"
Sorry, it took me a while to get that image.
you need to adjust xmin, xmax, etc
xmin = -10 xmax = (largest x value) + 10 ymin = -10 ymax = (largest y value) + 10
Yeah, thats what they are set at
Do you mean 100?
the largest x value is 74, so xmax = 74+10 = 84 the largest y value is 74, so ymax = 74+10 = 84
xmin = -10 xmax = 84 ymin = -10 ymax = 84
that will ensure every point is visible and not offscreen
Ooh, okay. Alright, I can get it from here.
Thank you for your time
