First, the slope is the constant rate of change of a line.

The 7 definitions of are:
1.Steepness of a line
2.M (variable that represents slope)
3.Vertical change over horizontal change
4.Rise over run
5.Change in y over change in x
6.Rate of change
7.Change of output over change input

There are 4 types of and they are:
Positive, it goes up to the right
Negative, down to the right
Zero, a horizontal line
Undefined (no slope), it is a vertical line

Slope intercept form is the equation used for a linear function. The equation looks like this, y=mx+b. (x,y) are your coordinates, m is slope, and b is your y-intercept.

1. With the y intercept (b) go up that many spaces on your y-axis.

2. Starting at your y intercept, graph your slope

3. It should form a straight line, if it does then your done

*The slope of a line is determined by the ratio change in y change in x between any two points that lie on the line.

*Remember if the slope is negative the line goes down, if it is positive the line goes up *

To find Slope from a table you must find the pattern of the x coordinates and the y coordinates.

*Refer to the Graph below*

> To find slope on a graph you must find two points that the line intersects with the grid.
> To find the Y-intercept you must look for the point where the line connects to the y-axis.
> Then all you have to do from there is put it into slope intercept form.

1. Take the two ordered pairs(from your line)and put them so you are subtracting one ordered pair from another. The y coordinates should always be on the top.                     y^1- y^2 over x^1- x^2

2. Next, solve the equation.

*The solution you have is the slope of the equation

3. To find the y-intercept take one ordered pair and plug it into the equation, solve it like an algebraic equation.

4. Finally solve. The solution is your y-intercept.
