Slide 1

Slope basically describes the steepness of a line

Slide 2

If a line goes up from left to right, then the slope has to be positive

Conversely, if a line goes down from left to right, then the slope has to be negative

Slide 3

Slope is simply the change in the vertical distance over the change in the horizontal distance

Slide 4

The formula above is the one which we will use to find the slope of specific lines

In order to use that formula we need to know, or be able to find 2 points on the line

Slide 5

If a line is in the form Ax + By = C, we can use the following formula to find the slope:

Slide 6

Examples

Slide 7

Horizontal lines have a slope of zero while vertical lines have no slope

Horizontal

Vertical

m = 0

m = no slope
