and
Are the lines parallel, perpendicular, or neither?
if they have same slopes, they will be parallel
if their slopes are negative reciprocals, they will be perpendicular
if not neither of above, then lines neither parallel nor perpendicular
check if they have same slopes:
...slope is
=>...slope is
as you can see, they have same slope; so, your lines are
graph them:
since you have linear functions, graph will be a line and you need only two points to graph each line
easiest is to find and
...set
x-intercept is at (, )
...set
y-intercept is at (, )
now
...set
x-intercept is at (, )
...set
y-intercept is at (, )
plot these points and draw a graphs:

Parallel. They both have a slope of 5 and unique y intercepts.
