special post

Hi,
 today we have a special post.I do one of these every 20 posts.As we all know Earth day is coming up.So I have come up with some ways to help the earth.Number 1.Try to pick up trash when you see one the ground.It is important that we keep our planet clean.Number 2.Try to recycle and reuse glass bottles and news papers.Don't put food scraps into the garbage, try to make compost out of it.Number 3.
Try to not drive the car as much and ride bikes instead.Number 4.You could plant a tree to produce more seeds to grow more trees.Trees are the source to our lives.Trees give us the shade we need and the air we breath.

And the most important,NUMBER 5.Do every thing you can to protect the earth.The earth is the place we live.We would all not be here with out it.It is our home that we must protect.The earth is the source of our food and water.So you see we must protect it.So get out and HELP THE WORLD.You can make a difference.

slope 2

Hi,
Today we are going to continue talking about slops.In this post we are going to talk about horizontal lines or no slope, undefined, and a short cut to find slope without graphing.No slope is when you graph it and it comes out in a horizontal line and undefined is when it is A straight vertical line.


The short cut is to take the 2 points and subtract x from the other x and y from the other y.Once you are done put y over x in fraction form and simplify.Keep it in a fraction always.That would be the slope.You can only use this way if you have 2 points.

slopes

Hi,
today we are going to talk about slopes.To find slope you must know how to graph points.Slope is the measure of steepness of aa line.The ratio of the vertical over horasontal.A line with a positive slpoe goes upwards and a slope with a negitive slope is going downward.

The formula is always y=mx+b.M stands for the slope and b stands for the y-intercept.If it is a horisantle line it is a no slope or 0 slope.If it is vertical it is undifined.Once you have the slope and one point you can find the other points and find the line.We will continue this next post.
