How do you find the slope of the line containing points with the coordinates (-4, -5) and (4, 4)?
Slope (gradient) is all about rate of change.
You always read left to right on the x-axis (unless stated otherwise)
The left most
Set point 1 as
Set point 2 as
Slope (gradient) is the change in up or down for a given amount of along.
If the change is down then the gradient is negative.
If the change is up then the gradient is positive.
Set gradient as
