So today we learned how to graph a linear function (which is an equation with 2 variables and no exponents. We graph this by using a t-table. Plug in the value for x and get the value for y.
For example:
y=2x
x y
-1 -2
0 0
1 2.
From this t-table you create ordered pairs and graph them. If you've done it correctly, they will lie in a line.
We also learned about slope. To find the slope, choose any two points on the line. If you count up (the rise) and across (the run) and divide (rise over run) you will have the slope.
For homework tonight you have 4 equations to graph and every period but Period 1 needs to find the slope.
The equations are
1) y=3x-2
2) y=x
3) y=x+1
4) y=1/2 x.
good luck and see you tomorrow:o)

Hi Ms. V!!!
It was my B-Day today!!!!
Have a nice day!!!!!
LINEARIE FUNCTIONS AND SLOPIE!!!
FLORIE---*^^*!
So we only need THREE coordinates?? In the T-CHART??
AHH! I'm confused!
FLORIE---:(
Whee! Liney Functions! Happy Birthday Florie! slope=rise over run- oops I fell. Note to self: try getting up before sprinting to dinner.
NOTE TO SELF----TRY SITTING UP BEFORE running a mile! TRY RISING UP from your hand before getting a work out, or you won't look ANY different!!!!!!
FLORIE--HA HA!*^^*
Thanx Manuel!
Hi Mrs. Vickery!!!
This Is SOOOOOOOO! Easy and fun to do. I hope we will be able to do a lot more of them.
