Geometry question, someone pleaseeeee help me with it!!!

Answer:
(-7,4)
Step-by-step explanation:
MN is 4/9 NP so
To find the x value
-19 and 8 are 27 apart and 27(4/9)=12
so you add 12 to the x value of P so 12+-19=-7 so the x value of N is -7
so the same for the y value
12 and -6 are 18 apart
18(4/9)=8 so you subtract 8 from the y value of P
12-8=4
so the y value N is 4
so N is
(-7,4)
These 3 problem I have answered have been almost the same except the numbers do you not understand how to do these problems and if not I can help you understand for the last question?
Answer:
The coordinate of N is (-7,4)
Step-by-step explanation:
MN + NP = MP
We know that MN is 4/9 of MP
First we will look at the x distance
That total x distance is
-19 to 8 or 27 units
4/9 of 27 is 12
Add this to coordinate of M
Add 12 to -19 = -7
Now we will look at the y distance
12 to -6 or 18 units
18 * 4/9 = 8
Subtract this from coordinate of M since we are going down
12 -8 =4
The coordinate of N is (-7,4)
