I am having trouble with the following question;

y+7=8x

2x-y=-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=8x-7

second line is

y=2x-7

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
