What is a line of best fit on a scatter plot? How can you estimate a line of best fit?...

From David Tate

Sometimes we need to go deeper in describing relationships between variables. More than positive, negative, or no relationship. The key is looking at how the x-variable affects the y-variable. "as the x-value increases, the y-variable _________."...

This video is a little different than my others. I'm using a bluetooth microphone that can pick up my students' voices as well. What you'll see is a normal lesson...... The key to these function word problems are identifying the rate of change (slope) ...

From David Tate

At this point you should already know how to find the rate of change from a table or graph. You should also be able to know that rate of change is abbreviated as k. Finally you should be able to already build an equation to represent a proportional re...

From David Tate

The rule is simply an equation. Find the slope (m) and then plug it into point-slope to find the equation. Examples of finding the rule given in this video....

From David Tate

This lesson assumes you can identify proportional relationships and find their rate of change. Now we explain that rate of change's abbreviation is k, and if you know k..... simply use the template y = kx. If k = 2, then the equation for the proportion...
