# 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.

Gradient is

To find the slope of the line containing the points (-4, -5) and (4, 4), you use the formula for slope: ( m = \frac{{y_2 - y_1}}{{x_2 - x_1}} ), where ( (x_1, y_1) ) and ( (x_2, y_2) ) are the coordinates of the two points. Substituting the given coordinates into the formula, you get ( m = \frac{{4 - (-5)}}{{4 - (-4)}} ). Simplify this expression to find the slope.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
