@Mertsj

OpenStudy (mertsj):

Solve both equations for y

OpenStudy (mertsj):

Did you get y= - 2x for the first one and y=3x+10 for the second one ?

OpenStudy (anonymous):

@Mertsj yes, so put them in y=mx=b?

OpenStudy (mertsj):

Yes. y = mx+b

OpenStudy (mertsj):

Do you have graph paper?

OpenStudy (anonymous):

@Mertsj yes

OpenStudy (mertsj):

Let's graph the first one. y = -2x + 0 Do you know that the y intercept is 0?

OpenStudy (anonymous):

@Mertsj yes, but isnt the two a negative number?

OpenStudy (mertsj):

Yes. That's what y = - 2x + 0 means. that little line in front of the 2 means that it is negative.

OpenStudy (mertsj):

Since the y intercept is 0, mark 0 on the y axis on your graph paper.

OpenStudy (anonymous):

@Mertsj oh sorry i meant, positive?
