Answer choices are 2x plus y = - 5, 2x - y=5

X + 2y=-10

y = - (1/2) x - 5 which comes from x + 2y = - 10

Step-by-step explanation:

The question was which equation is equivalent to y = (-1/2) x - 5 I think.

In that case, we need to solve these equations to get an answer.

2x + y = - 5 gives

y = - 2x - 5 which is not the answer you want.

2x - y = 5 gives

y = 5 - 2x by subtracting 2x from both sides, and this is not the answer.

x + 2y = - 10 Subtract x from both sides.

2y + x - x = - x - 10 Combine on the left.

2y = - x - 10 Divide by 2

2y/2 = - x/2 - 10/2

y = - x/2 - 5 Answer
