The slope of a line is the vertical change divided by the horizontal change... or... the change in y divided by the change in x.
Using the points (-6,-4) and (-2,5)...
The change is y is 9
The change is x is 4
The slope is 9/4

To find the slope of any line the equation is Delta Y/ Delta X, which is long for change in the Y divided by the change in X.
The change in X = -6- -2 = -4
The Change in Y = -4 -5 = -9
Therefore the slope of the line passing through those points is 9/4. (Two negatives make a positive).

The slope of a line is defined as the change in y over the change in x. Think of the two points as (x1, y1) and (x2, y2). To find the slope, in general, the formula is:
slope = m = (y2 - y1)/(x2 - x1)
For your problem, let (x1, y1) = (-6, -4) and (x2, y2) = (-2, 5)
Then, the slope is m = (5 - -4)/(-2 - -6)
= (5 + 4)/(-2 + 6) (simplify the - signs)
= 9/4
The slope is then 9/4 = 2.25.

Slope is the change in y values divided by the change in x values:
(-4 - 5)/(-6 - -2) = -9/-4 = 2.25

if (x1, y1) and (x2, y2) are the two points, then the slope of the line passing through the two points is
(y2-y1)/(x2-x1)
