Today we have a test on Topic 18 – Formulas and Equations. It basically comes down to this; If given y = x + 3, what is y if x=4? Or, if I want to be more difficult, if y=3x, what is y if x is 4? And then we go backwords:
x 1 2 3 4 So what is the rule?
y 0 1 2 3 Answer? y=x-1
Then for a couple, I gave them the rule, and they had to figure out what x and y were, and they graph the ordered pairs. They love doing that.
We’ll see how they do on the test.
Next topic? 14 – Integers.
Anyone know what an integer is?
