alec calculated the slope of line ac between points a and b. avis calculated the slope of line ac between points b and c. both alec and avis drew triangles, as shown below, to calculate the slopes:

a graph shows numbers from 0 to 18 on the x axis at increments of 2 and the numbers 0 to 6 on the y axis at increments of 1. a line ac is drawn that joins the ordered pairs 0, 0 and 18, 6.the ordered pair 6, 2 is labeled as b. a right triangle is drawn with ab as hypotenuse and height 2 units. another right triangle is drawn with bc as the hypotenuse and height 4 units.

which statement is correct about the slopes calculated by alec and avis if both calculated the slopes accurately?

both calculated the slope as 3.
both calculated the slope as 1 over 3.
alec calculated the slope as 1 over 3 and avis calculated it as 3.
alec calculated the slope as 3 and avis calculated it as1 over 3.
