Finding the slope of a line:

Finding the slope of a line To find the slope of the graph of any linear equation, you must first locate two points on the graph. Point Point

Finding the slope of a line:

Finding the slope of a line Starting with the point on the left, count how far up or down you must go to be level with the other point. This is called the RISE . If you go up the rise is positive, if you go down the rise is negative. The point will go u p 5 places so t he rise is 5

Finding the slope of a line:

Finding the slope of a line Now, go to the right until you reach the other point. This is called the RUN . The run is 10

Finding the slope of a line:

Finding the slope of a line To calculate the slope, use the formula: Slope = Rise Run In our example the rise was 5 and the run was 10, so our slope would be: Slope = Rise = 5 = 1 Run 10 2 The slope of our line is ½.

Finding the slope of a line:

Finding the slope of a line There are two special types of lines that we need to consider as well Horizontal – All horizontal lines will have a rise of 0 and thus, their slope will be 0. Vertical – All vertical lines have a run of zero and since division by zero is undefined, we say that a vertical line has “ No Slope”.
