I am having trouble with the following question;
y+7=8x
2xy=7
Determine whether the lines will be parallel. My answer is yes am I correct?

Are the slopes the same? Did you solve for the slope? I don't think the slopes are equal.

For the equation of a line in the form:
y = m*x + b
m=slope
b=y intercept
The lines will be parallel if the slopes (m value) are the same.
Rearrange the equations to the above form and check for m being the same value for each. 
y=mx+b
first line is
y=8x7
second line is
y=2x7
as m is not same ,that is slope is not same ,lines are not parrellel 
ok on the first one I have m=8 and the second one the m=2 which would make them not the same.which would make them not paralel
