jimthompson5910 (jim_thompson5910):

the slope one?

OpenStudy (anonymous):

yes. then there is another one in the attachment

jimthompson5910 (jim_thompson5910):

what did you get for the slope one? what work do you have so far?

OpenStudy (anonymous):

not sure how to do it correctly.

jimthompson5910 (jim_thompson5910):

did you use the slope formula?

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

yes you use that

OpenStudy (anonymous):

y is the second and x is the first

jimthompson5910 (jim_thompson5910):

yes that is correct

OpenStudy (anonymous):

-1?

OpenStudy (anonymous):

i did it wrong. ill fix it

OpenStudy (anonymous):

-0.2

jimthompson5910 (jim_thompson5910):

(–2, –1) and (8, –3) -3 - (-1) = -3+1 = -2 8 - (-2) = 8+2 = 10 so we have -2/10 = -1/5 as the slope

OpenStudy (anonymous):

so it is b?

jimthompson5910 (jim_thompson5910):

yeah

OpenStudy (anonymous):

ok. now i need help with the attachment

jimthompson5910 (jim_thompson5910):

in each row, divide y by x

OpenStudy (anonymous):

-4

OpenStudy (anonymous):

4

OpenStudy (anonymous):

it is +4

jimthompson5910 (jim_thompson5910):

yes +4

OpenStudy (anonymous):

it is c

jimthompson5910 (jim_thompson5910):

yep
