Solution:
Coordinates of Point E and F are (-2,4) and (5,10).
Suppose the Point M(x,y), divides the Line Segment Joining E (-2,4) and F (5,10) in the 7:3 ratio.
So, EM: MF= 7:3
Formula for internal Division


So,we get
x= 2.9
and , y= 8.2
1. Yes.
cranberry juice : total cups = 1 : 5 in all cases
2. Yes.
cranberry juice : total cups = 2 : 5 in all cases
3. No.
1 : 5 is not the same as 2 : 5.
Slope= 5
X-intercept= -5/5 = -1
Y-intercept= 5/1 = 5.0000000
