math help !! :) thanks!

X= (-7,12)
Y= (7,-9)
The distance between the x points is 14 units
we want a ratio of 3 to 4
for every 3 on one side there are 4 on the other for 7 total
6 to 8 = 14
so 6 on one side 8 on the other
so 6 units on the left starting at -7
-7 + 6 = -1
same with y
12 to -9 is 21 units
3 to 4 = 7
6 to 8 =14
9 to 12 = 21
so 9 unit from the top
12-9 = 3
(-1,3)
Choice A
Answer:
Its A
Step-by-step explanation:
If we examine the x values of X and Y we see that the vertical distance between them is 21 units
So the required y coordinate of the required point will be (3/7) * 21 = 9 points down from X ( its 3/7 because the ratio is 3:4 )
So from the graph we see that the point on the line has (12-9) = 3 as the y coordinate
Answer is (-1, 3)
