Question: find the slope of the line that passes through these two points. (1,3) (4,6)
Solution:
By definition, the slope of a line is given by the following equation:
where (X1,Y1) and (X2,Y2) are points on the line. In our case, we can take the points:
(X1,Y1) = (1,3)
(X2,Y2) = (4,6)
and replace them into the slope equation:
then, we can conclude that the correct answer is:
