@Destinymasha

OpenStudy (haleyelizabeth2017):

plug the points into m=y2-y1/x2-x1

OpenStudy (anonymous):

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

OpenStudy (haleyelizabeth2017):

the points are (-1, 3) which is -1=x1, 3=y1 and (4, -7) which is 4=x2, -7=y2 don't forget a subtracting a negative is the same as adding a positive

OpenStudy (anonymous):

so is it 3/4 @haleyelizabeth2017

OpenStudy (haleyelizabeth2017):

nope try again! -7-3 over 4--1

OpenStudy (anonymous):

ooh i got -4/3 :P

OpenStudy (anonymous):

dont think thats right tho

OpenStudy (haleyelizabeth2017):

nope what is 7+3? thats the same as -7-3 but you need to add a negative...... and 4--1 is the same as 4+1 lol

OpenStudy (haleyelizabeth2017):

so it is -2....

OpenStudy (anonymous):

i was about to type that XD

OpenStudy (anonymous):

is this the same way? What is the slope of the line passing through the points (0, −5) and (4, 2)?

OpenStudy (haleyelizabeth2017):

OpenStudy (haleyelizabeth2017):
