Step-by-step explanation:
Line is passing through the points 
Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3
Equation of line in point-slope form is given as:

Plugging the values of
in the above equation we find:




This is the required equation of line in the form 
Answer:
D’=(3,3); F’=(-2,-2); E’= (-5,0)
Step-by-step explanation:
