Answer:
(2,-4)
Step-by-step explanation:
When a point (x,y) is reflected across the y-axis, you need to change the sign of x. For example, if (-x,y) you need to take away the negative sign, which makes (x,y). Or, if the point is (x,y), you need to add a negative sign to the x, which makes (-x,y). So, if your point (-2, -4) is reflected across the y-axis, you need to take the negative sign off the -2, which makes (2,-4).
68 is the answers that it I guesss
Answer: The correct option is (B) 
Step-by-step explanation: We are given the following system of equations :

We are to find the equation that could be the result of using substitution to solve the above system.
Substituting the value of x from equation (i) in equation (ii), we get

Thus, the required equation is 
Option (B) is CORRECT.
