SO ANYTHING THAT EQUALS Y MUST CROSS THE Y ACCESS? SAME WITH X?
ReplyDeleteIn the coordinate plane, think about 'y=#' and 'x=#' (where # is any real number) equations from this perspective.
ReplyDeleteFor example, for y=7... where in the ENTIRE coordinate plane do ALL of the ordered pairs "reside" when the y-coordinate is equal to 7? Well, let's plot a few, such as (-4,7), (-1,7), (0,7), (3,7), (19,7).... hmmm do we see a pattern forming?? I hope so. All of these ordered pairs (aka coordinate pairs) reside on a horizontal line that intersects with the y-AXIS (not "access").
Robin (quizzically): Gee whiz, Batman, what's the best mathematical way we can describe this line?
Batman (knowingly): Well, of course, Robin, since this line happens fall where all of the y-coordinates are equal to 7, we can abbreviate.."
Robin (excitedly cutting in): to 'y=7', right Batman!!??
Batman (in a fatherly tone): Yes, Boy Wonder, you've done it again!
Alfred (proudly): Well done, gentlemen. I knew you would get it! Perhaps some tea to celebrate?
The same one-act play could be written for vertical lines. All vertical lines in the coordinate plane will intersect the x-axis and be defined by an 'x=#' equation.
N.B. btw everyone: YOU WILL GET THIS WRONG on the QUIZ and the TEST. So why not study it NOW and LOCK IT IN your memory banks!!??
Mr. C.
thanks for believing in us....just kidding :)
ReplyDeleteI'm just trying to get you FIRED UP!! So KEEP YOUR EYE ON THE BALL, OK?!
ReplyDeleteI was looking over my work and realzed that i only used white lined paper and not graph paper, is that ok?
