Thank you for the opportunity to help you with your question!

x-2y=6

Rewriting the equation in the form y=mx+c gives

-2y=-x+6

divide all sides by (-2) gives

y=1/2x+3

For parallel lines, the gradient/slope is the same

therefore: m = 1/2, (-5,2), (x,y)

1/2=(y-2)/(x--5)

1/2=(y-2)/(x+5)

simplifying the expression gives

y=1/2x+9/2

The answer is A

Please let me know if you need any clarification. I'm always happy to answer your questions.
