Answer:
m = Δy / Δx
m = (4 - 1) / (4 - 5)
m = 3 / -1
m = -3
(4,4) (5,1)
Slope = Change in Y Change in X
4 - 1
4 - 5
equals 3/-1 or -3
Step-by-step explanation:
The slope of a line is often called "rise over run" because it is the increase in y-values divided by the increase in x-values. It is also called grade/gradient, slant, incline, ramp, ...
A positive slope means that the line goes up as you move right on a graph. A negative slope means that it goes down. A zero slope means that it is horizontal (level).
