Parallel lines means that they have the same slope.

anonymous · Answer

if the first formula is y=8x-2 the slope is 8.

whpalmer4 · Answer

yes, parallel lines will have the same slope.  if the equation is in slope-intercept form, it will look like $$y = mx + b$$ where $m$ is the slope and $b$ is the value of the y-intercept

There's a "trap" answer here, don't be fooled!

how can I solve this?

whpalmer4 · Answer

look at all the equations.  find one that can be rearranged into the form $$y = 8x +b$$ where $b$ is some constant.

im really confused? is it like C because of the 8x?
