Answer:

The coordinate of point A is -138

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

[tex]M(\frac{x_1+x_2}{2})[/tex]

In this problem

[tex]x_1=-100\\M=-119[/tex]

substitute

[tex]-119=\frac{-100+x_2}{2}[/tex]

solve for x_2

[tex]-119(2)=-100+x_2[/tex]

[tex]x_2=-238+100\\x_2=-138[/tex]

therefore

The coordinate of point A is -138
