1)
The equation is written in y = mx + b form, so m is the slope. m is what multiplies x. In your case, -4/5 multiplies x, so -4/5 is the slope.

2)
To find the slope, subtract the y-coordinates. Then subtract the x-coordinates in the same order. The slope is the first difference divided by the second difference.

Difference in y: 1 - 5 = -4
Difference in x: 4 - 2 = 2

m = slope = -4/2 = -2
