2.8 or if rounded to the nearest tenth so 2.8√8
Step-by-step explanation:
eqn of line : y = mx+ c
m = slope or gradient
c = y-intercept.
Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

Substitute x = 1 and y = 6 into equation,

Therefore substituting m and c value, equation of line is

E=mc^2 if m=3 and c=6
e=3(6^2)
e=3(36)
e=108
