Linear Function

A linear function is a function of form f(x)=mx+b, where "m" is the slope and "b" will be "y" intercept

1. $m=slope={rise \over run}={dy \over dx}$
2. rate of change = d = Δ
3. Δx = rate of change of x = dx

Properties

1. linear function has a constant rate of change
2. one functions slope will aways be the same
3. When linear function f(x)=mx+b is increasing, if m > 0
4. When linear function f(x)=mx+b is decreasing, if m < 0
5. When linear function f(x)=mx+b is Constance, if m = 0
