# Example of shapes on a coordinate plane

Plotting points on a coordinate plane can help us draw shapes like rectangles! The points (1,1), (1,6), (9,6), and (9,1) form a rectangle. The x-coordinate tells us how far right to move, and the y-coordinate tells us how far up to go. The rectangle's height is the difference between the y-coordinates, which is 5.

• I agree with Sushay,math may seem boring,but it can actually be useful,it helps you how to use money properly.

Imagine you are a tourist in a bazaar,
you only have 70 dollars in your wallet,then you see a curio shop called 'Acra Dacra's Magic Shop' where it sells strange magical items,the shopkeeper,Acra Dacra,shows you what he has for sale:

Magic Carpet 10\$

Genie Lamp 20\$

A Magical Ring that can turn you invisible every time you wear it but turns you into a creepy guy walking on fours eating raw fish for enternity 19\$

Ruby Slippers 35\$

Monkey Paw 45\$

A Ballpoint Pen that can turn into a sword named Riptide 55\$

If you buy one of his items,how much money will you have left?
• I would have \$50. As seen in Aladdin, their incorrect physics of when they flew on the magic carpet would make the air resistance instantly k!ll you, so I wouldn't buy that. The magical ring has obvious downsides, so I obviously wouldn't buy it, plus I don't react well with fish. I doubt the ruby slippers would be comfortable, assuming that the slippers are made entirely from ruby. I woudn't buy the monkey's paw because I do my research, and The Monkey's Paw (the book) is of the horror genre, and I'm pretty sure something bad would happen if I bought it. Lastly, I don't have use for a sword (or a pen, but only because I already have plenty good pens). If you take all of this information, it would only be logical to take the genie lamp.
• There are so few questions
• i got confused at minute 1;01
• At minute , Sal just described where the points were located at. That's not so important but can help to few.
• Can a shape have more than 4 vertices and only 4 sides?
• A shape should have the same number of sides as vertex points. So, I don't think so. Imagine that you had to come up with the answer to it. Think of the shapes you know, and see if there are any more vertices than sides.
• so if you were to have to solve the height without being able to look at the cordinate plane would you just take the larger number in that column and subtract it with the smaller one?
• Who Doesn't understand? I can help.
• I tend to be good at math, but overall I'm struggling in this subject (Coordinate grids) and just to keep up with my Kahn academy. Can someone help me out?
• Hey Kennedy! I too struggle at math, and don't enjoy it. But you should try AI Tutoring... it can really help you! You could pay and use the one on Khan Academy, or you can you the one on Brainly for free. You should try it! Hope this helps! ✌︎ ♡ ☺︎ ☆
