The slope is 1010.

Explanation:

Slope is "rise"/"run"riserun, or the change in the yy coordinate divided by the change in xx.

Mathematically this is written

(deltay)/(deltax)δyδx

To calculate change in a coordinate, take the second one and subtract the first.

deltay = 8 - (-2) = 10δy=8(2)=10
deltax = -3 - (-4) = 1δx=3(4)=1

Therefore the slope is

(deltay)/(deltax) = 10/1 = 10δyδx=101=10

10

Explanation:

Slope is rise over run, in other words, the change in the yy divided by the change in xx.
'Change in' is the difference between the numbers, so
(y_2-y_1)(y2y1) divided by (x_2-x_1)(x2x1)

(8- -2)/(-3- -4) =(10)/(1) = 108234=101=10
