@acxbox22 @Nnesha

Nnesha (nnesha):

find the slope first of both lines

OpenStudy (acxbox22):

the y intercepts are different so they arent the same line

Nnesha (nnesha):

if both slopes are same then its mean you have parallel lines which mean no slope

OpenStudy (acxbox22):

which means no solution

OpenStudy (acxbox22):

@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

OpenStudy (acxbox22):

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):
