At the beginning of class we talked about the home work we where assigned the day before.
Which was the graph for diagonal lines.
Let s = sections
Let d = diagonal sections
Section times 4 is diagonal section
4s = d
Also for homework we needed to do a Show You Know question as well. This is on page 344 of the textbook at the bottom.
Page 345 Show You Know Question and solution:
At the top of the chart (part A) it goes up by +3
At the bottom part of the chart (part B) It goes up by +9
So table 1 does show a Linear Relation
At the top of the chart (part p) it goes up by +1
At the bottom of the chart (part q) it goes up but +1, +1, +3
So table 2 does not show a Linear Relation
Next we did a solution on page 346
It asked to show what the Linear Relation was.
And as you can see here the linear relation for part n is +1 and for part c is +3
Also if you have part n while you are trying to find the answer for part c.
the expression is 2n+1
a) Let n = subscriptions
Let p = pay
c) she will receive $160 is she sells 40 subscriptions
