Answer:
Option 2 ( 1,-10)
Step-by-step explanation:
The two equations are y = -x²-5x-4 -----(1)
and y = -x²+9x-18-------(2)
To get the solution of these lines we will substitute the value of y form equation 1 to 2.
- x² - 5x -4 = -x²+9x-18
Now by collecting similar terms on each side.
-x² -5x + x²-9x = -18 + 4
-14x = -14
14x = 14
x = 1
By putting the value of x in equation 1.
y = -1 - 5 - 4 = -10
So the solution is (1, -10)
Therefore Option 2 is the correct answer.
