This table shows the input and output values for a linear function f(x).
What is the difference of outputs for any two inputs that are one value apart?
The absolute value for any inputs that are one unit apart is 25
We can see this by taking the absolute value of the slope between any two consecutive inputs
l [ -5 - 20 ] / [ -1 - -2] l = l -25 / 1 l = 25
