with what

OpenStudy (mikezack123):

OpenStudy (mikezack123):

with that

OpenStudy (anonymous):

did you try doing the whole y2-y1 / x2-x1

OpenStudy (mikezack123):

how i do that

OpenStudy (mikezack123):

jimthompson5910 (jim_thompson5910):

We're focusing on the two points (3,7) and (-2,-8)

OpenStudy (mikezack123):

okay

jimthompson5910 (jim_thompson5910):

to find the slope of the line through them, use the slope formula \[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

jimthompson5910 (jim_thompson5910):

so you subtract the y coordinates then subtract the x coordinates in the same order and divide the two differences (y over x)

OpenStudy (mikezack123):

-8-7/-2-3

jimthompson5910 (jim_thompson5910):

keep going

OpenStudy (mikezack123):

so it would be -15/-5

OpenStudy (mikezack123):

which equals 3

OpenStudy (mikezack123):

so the slope would be 3/1 ?

jimthompson5910 (jim_thompson5910):

or 3, which is simpler

OpenStudy (mikezack123):

yes its fill in the blank what should i put? 3 or 3/1 ?

OpenStudy (mikezack123):

actually ill just ask my teacher. thank you very much!

jimthompson5910 (jim_thompson5910):

I'd put in 3

jimthompson5910 (jim_thompson5910):

but that works too

OpenStudy (mikezack123):

okay thanks again! :)
