Math help !! :) thanks!

Answer 1

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)

Answer 2

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
