find the slope first of both lines
OpenStudy (acxbox22):
the y intercepts are different so they arent the same line

if both slopes are same then its mean you have parallel lines which mean no slope
OpenStudy (acxbox22):
which means no solution

@Nnesha
Nnesha (nnesha):
yesh solution**
both have s so i switched IO_O
Nnesha (nnesha):
thanks

OpenStudy (itsbribro):
so i have to find the slope of each line?
OpenStudy (acxbox22):
yes
OpenStudy (acxbox22):
if they are the same then it is no solution
if the slopes are different then there is only one solution
OpenStudy (itsbribro):
okay well their slopes are the same
OpenStudy (itsbribro):
oh ok

good job, since the slopes are the same then it is no solution since they are parallel and will never intersect
Nnesha (nnesha):
yesh if both slopes are same then they have parallel lines mean no slope
OpenStudy (itsbribro):
thank you both :)
Nnesha (nnesha):
