m = change in y / change in x

OpenStudy (anonymous):

m= (y2-y1)/(x2-x1)

OpenStudy (michele_laino):

the requested slope m, is given by the subsequent formula: \[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}\] where (x_1, y_1) and (x_2,y_2) are two points which belong to your line. So picking the first two points, and substituting their coordinates, into the formula above, we get: \[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{ - 3 - \left( { - 5} \right)}}{{0 - \left( { - 3} \right)}} = ...?\]

0.375

OpenStudy (i_love_my_nieces):

I mean 1.5

OpenStudy (michele_laino):

I got this: \[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{ - 3 - \left( { - 5} \right)}}{{0 - \left( { - 3} \right)}} = \frac{2}{3}\]

OpenStudy (i_love_my_nieces):

oh I though you meant divide it I go 2/3

OpenStudy (i_love_my_nieces):

But thank you tho!

OpenStudy (michele_laino):

thank you!
