The slope is [y2 - y1]/[x2 - x1]
= [2 - (-3)]/[(-2) - (-8)]
= 5/6

To find the slope of a line passing thru the points (-8,-3) and (-2,2):
m = (y-y1) / (x-x1)
m = (-3-2) / (-8-(-2)) = -5/-6
m = 5/6

m=(y1-y2)/(x1-x2)
where
m is the slope
in point (-8,-3) the first refers to your x1 and the second to your y1
same in the point (-2,2) -2 will be set as x2 since this is your second x coordinate and 2 is your y2 with the same reason substituting the values to the given formula for slope will yield the equation
m=(-3-2)/(-8-(-2))
m=(-5)/(-6)
m=5/6 this is your slope

The formula for slope is [different in y]/[different in x] or δy/δx
For a line passing through the points (-8,-3) and (-2,2),
δy = 2-(-3) = 5
δx = -2-(-8) = 6
Hence, slope = δy/δx = 5/6

Use gradient, m to determine the slope of the line. How? Use this formula.
m=(difference between two y-coordinate)/(difference between two x-coordinate)
Given (-8,-3) and (-2,2)
m=(2-(-3))/(-2-(-8))
=5/6
So, the slope/gradient of the line is 5/6.

The formula for the gradient of a line passing thru two points is: m = (y2 - y1)/(x2 - x1). Therefore, in your particular case, the gradient m = [2 -(-3)]/[-2-(-8)] = 5/6. Expressed as an angle(theta) inclined to the x-axis, theta = arc tan(5/6) = 39.8 deg

The formula for the slope of the line is m=(y2-y1)(x2-x1)
So in the given problem, y2=2; y1=-3; x2=-2; x1=-8
Hence slope m=(2-(-3))/(-2-(-8))
= 5/6

Find the slope
Slope formula
m = y₂- y₁/x₂- x₁
Ordered Pair
(- 8, - 3)(- 2, 2)
m = -3 - 2/-8 - (- 2)
m = - 5/ -8 + 2
m = -5 / - 6
m = 5/6

The slope is 5/6, I think.
I got it by
(-2,2)
-
(-8,-3)
=(6,5)
=5/6
So you simply subtract them.
So you simply subtract them.

I would, but this tutorial does it better than I do and they even have pretty boxes, graphs, and examples that will help you really learn it.

You'll have it in no time. Good luck on your work.
