Answer: The correct answer is C. 1.
Explanation:
To find the value of y that makes the equation -2y - 9 = -11 true, you can follow these steps:
Add 9 to both sides of the equation to isolate the term with y on one side:
−2y=−11+9
−2y=−2
Divide both sides of the equation by -2 to solve for y:
y=−2/−2
y=1
So, the value of y that makes the equation true is 1. Therefore, the correct answer is C. 1.
