Math 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)

origin- the point of intersection of the x and y axis on a coordinate or Cartesian plane

x-axis- the horizontal axis of a graph

y-axis- the vertical axis of a graph

coordinates- shown as pairs of letters and/or numbers used to show position on a coordinate plane or map

x-coordinate- the position of a point according to the x axis

y-coordinate- the position of a point according to the y axis

quadrant- any quarter of a plane divided by an x and y axis

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.
