After
completing this section you will be able to define slope, and find
the slope of a line given it's graph or given two points on the
line. You will also be able to identify the slopes of horizontal
and vertical lines.
Training
Part 1: Warming Up
Every good runner
starts their training by warming up. They remind their muscles how
to move and they stretch them so they are ready to be pushed. In
your warmup you will explore linear equations and slope to remember
what you have learned about them and prepare to learn more.
Spend some time
experimenting with the linear equation graph below. When you are
ready, answer the questions below in your training manual.
Questions to
answer in your training manual:
1) What does
the line look like when the slope is positive?
2) What does
the line look like when the slope is negative?
3) What does
the line like when the slope is zero?
4) What does
the line look like when the slope is undefined?
5) Based on your
findings, write a definition of slope in your own words. Don't worry
if your not sure, we will check and revise your definition later
on.
Feel free to
continue playing with the graphing tool, and move on to the next
page of this section when you are ready.
