Yesterday April 14th we learned about linear equations and to create tables of values. Mr. Backe also told us about www.mathplayground.com and play some Math games.

He introduced Chapter 6 with some new words:

linear relation-A relation that appears as a straight line when graphed.

linear equation-An equation whose graph is a straight line.

interpolate-To estimate the value between two given values.

extrapolate-To find values that is not given

Tables of Values and linear equations

First thing to remember is that x is always the independent and y is the dependent.

Here's an example of a table of values in our class

To get the linear equation you have find the difference in each number in the y column. In this table it is 3, because it adds 3 in each row in the y column. And why -2, here's an example:

Practice Question from class

1. How many circles are in figure 7?

2.83 circles is what figure number?

Today April 15th we just corrected our tests and started to do work which is:
