Answer 2

Answer:

Alisha might have not taken respective input values with the output values and the correct slope is 3.

Step-by-step explanation:

The general form of a linear relationship is given by the equation

$y = mx+b$

Here m is the rate of change of the linear relationship which is calculated as:

$m = \frac{change\ in\ y}{change\ in\ x}$

Change in y is given by the difference of two outputs and x is given by difference of two inputs

So taking the set of outputs and inputs

(1,2) and (2,5)

$m = \frac{5-2}{2-1}\\m = \frac{3}{1}\\m = 3$

Alisha might have not taken respective input values with the output values and the correct slope is 3.
