Choose the correct slope of the line shown on the graph below.

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

identify two points on this line where each coordinate is a whole number

OpenStudy (anonymous):

three halves two thirds −three halves −two thirds

jimthompson5910 (jim_thompson5910):

one point is (3, -3) what's another one?

OpenStudy (anonymous):

4,-4...?

jimthompson5910 (jim_thompson5910):

no (4, -4) isn't on the line however, the point (6, -1) is on the line

OpenStudy (anonymous):

6, -1

jimthompson5910 (jim_thompson5910):

so we have these 2 points: (3, -3) and (6, -1)

OpenStudy (anonymous):

so whats the answer?

jimthompson5910 (jim_thompson5910):

start at (3,-3) how many units must you move up to be on the same horizontal level as the point (6, -1)

OpenStudy (anonymous):

uhh 6?

jimthompson5910 (jim_thompson5910):

from -1 to -3 we have moved ____ units

OpenStudy (anonymous):

3 to the right and 2 up

OpenStudy (anonymous):

2

jimthompson5910 (jim_thompson5910):

so the rise is 2

OpenStudy (nathan917):

give her a prize!

jimthompson5910 (jim_thompson5910):

we must move over 3 units to the right to land on (6, -1) So the run is 3

jimthompson5910 (jim_thompson5910):

rise = 2 run = 3

jimthompson5910 (jim_thompson5910):

slope = rise/run slope = 2/3
