Answer:
<h3> ( - 1 , - 1 )</h3>Option D is the correct option.
Step-by-step explanation:
y = - 2x - 3 → Equation ( i )
y = 3x + 2 → Equation ( ii )
Using elimination method
y + 2x = - 3
y - 3x = 2
---------------------
5x = - 5
Divide both sides of the equation by 5
Calculate
Again, Putting the value of x in equation ( ii ) in order t get the value of y
plug the value of x
Any expression multiplied by ( - 1 ) equals it's opposite
Calculate
Therefore, The possible solution of the system is the ordered pair ( x , y )
-----------------------------------------------------------------------
Check if the given ordered pair is the solution of the system of equation
Simplify the equation
Since all the equalities are true, the ordered pair is the solution of the system.
<h3>( x , y ) = ( - 1 , - 1 )</h3>Hope this helps..

Answer:
Step-by-step explanation:
So we know that:
To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:
Simplify:
And that's our answer :)
