<h3>Answer:  19</h3>

==============================================================

Explanation:

T is the midpoint of PQ, which means T splits PQ into two equal parts. Those parts being PT and TQ.

Set them equal to each other and solve for x.

PT = TQ

3x+7 = 7x-9

3x-7x = -9-7

-4x = -16

x = -16/(-4)

x = 4

So,

PT = 3x+7 = 3*4+7 = 19

TQ = 7x-9 = 7*4-9 = 19

Both PT and TQ are 19 units long to help confirm the answer.

Dmitrij [34]

Answer:

(-1,1)

Step-by-step explanation:

All you have to do is plug it in the equation:

      (x,y)

For (-1,1)

1=2(-1)+1

Simplify:

1=-1 but you know that 1≠-1 so (-1,1) is not it

For (3,7)

7=2(3)+1

Simplify:

7=7

For (-3,-5)

-5=2(-3)+1

-5=-5

Simplify:

For (0,1)

1=2(0)+1

1=1
