What are the asymptotes of the graph of y=3+ 5 ?

2x-6

What are the asymptotes of the graph of y =2-7 ?

x+18

The variable z varies directly with y and inversely with x. When x-4 and y = 28, z = 56. Which equation relates to x, y, and z?

z =8y

X

z=xy

56

z= 8xy

z= 56xy

Is there anyone that can help me??? PLEASE a mom that has long since forgotten this stuff trying to help daughter!!!
