Answer 3

1:3 ratio means there are 4 segments on the line (1 + 3 = 4). Start by finding the "length" of each segment in x an y.
\[x_{length}=\frac{ |x _2-x_1| }{ 4 }\]
\[y_{length}=\frac{ |y _2-y_1| }{ 4 }\]

Answer 4

xlength
5/4 and ylength= 7/5

Answer 5

7/4 for y.

Answer 6

soorry i meant 7/4

Answer 7

and then since you want a 1:3 ratio, add those to point D one time to get F.
