brb

OpenStudy (sachintha):

So what do you think about the slopes they got? Are they the same?

OpenStudy (alphina):

back

OpenStudy (alphina):

no

OpenStudy (sachintha):

The slope of the line from A to C is the same since it is a straight line.

OpenStudy (sachintha):

\(Slope = \Large\frac{\Delta y}{\Delta x}\normalsize=\Large\frac{y_2-y_1}{x_2-x_1}\)

OpenStudy (alphina):

so its either A or B?

OpenStudy (sachintha):

Yes

OpenStudy (alphina):

its b?

OpenStudy (sachintha):

Now calculate the slope from the smaller triangle. |dw:1463423030488:dw|

OpenStudy (sachintha):

Yeah it's correct!

OpenStudy (alphina):

yay thanks alright next question
