Answer:
Below
Step-by-step explanation:
To find the slope of the line you divide the difference in y values of the points by the difference of the corresponding x values).
So here the slope = (4-2) / (8-2}
= 2/6 = 1/3.
The student found it to be 3, so he could have divided the other way,
(8-2)/ (4 -2) =3. In other words he divided the difference of x-values by the y values instead of difference of y-vales divided by x values.
