definitions

Next, read pg. 353 and 354 from your textbook. Define all bolded words (skip abscissa) in your notebook (or on your blog if you want to) from those pages using this website, http://www.amathsdictionaryforkids.com/



Origin- point of intersection in the x and y axis.



x axis- horizontal axis of a graph



y axis - vertical axis of a graph



coordinates- a set of numbers or letters used to show postition on a coordinate plane or graph.



x coordinate- position of point acording to x axis.


y coordinate- position of point acording y axis

Coordinate plane- plane connecting a perpendicular plane

Two Variable equations

Next, read over pages 349 and 350 in your textbook. Then you can try a couple problems and post this on your blog. Do this by writing the equation for y in terms of x (ex. 3x + y = 7, so y = 7 -3x). Try #13-16 on pg. 351.

13. 2x+y=6 y= 6-2x

14. 5x+y=7 y= 7-5x

15. 3x+2y=8 y= 8-3x/2

16. 2x+5y=10 y= 10-2x/5
