OpenStudy (amistre64):

how do we define the slope of a line?

OpenStudy (amistre64):

.... no

OpenStudy (amistre64):

slope is defined as the change in y divded by the change in x

OpenStudy (amistre64):

simply subtract one point from the other, and stack y/x

OpenStudy (amistre64):

(-3, 5) - (1, 7) ------- -4,-2 ; then stack y/x

OpenStudy (anonymous):

2

OpenStudy (amistre64):

not 2, that would be x/y

OpenStudy (amistre64):

-2/-4 = 1/2

OpenStudy (anonymous):

oh well the nit would be switched to 1/2

OpenStudy (amistre64):

yes
