Find the slope of the line that passes through the points (0, -3) and (-4, 1). -1 -4 1 4 http://prntscr.com/8i31b1 http://prntscr.com/8i31ji

OpenStudy (madhu.mukherjee.946):

use the formula y2-y1/x2-x1

OpenStudy (madhu.mukherjee.946):

so answer will be -1

OpenStudy (anonymous):

ok and for the second one?

rishavraj (rishavraj):

analyze the graph u got two points they are (0 , -5) and (-5 , 10) now get the slope

OpenStudy (anonymous):

is the answer 3?

OpenStudy (anonymous):

@rishavraj

rishavraj (rishavraj):

\[m = \frac{ y_2 - y_1 }{ x_2 - x_1 }\]

rishavraj (rishavraj):

plug the values

OpenStudy (texaschic101):

(0,-5) ...x1 = 0 and y1 = -5 (-5,10)...x2 = -5 and y2 = 10 slope = (y2 - y1) / (x2 - x1) slope = (10 - (-5) / (-5 - 0) can you finish ?

rishavraj (rishavraj):

@kittymeow101 done??? its not 3

OpenStudy (anonymous):

i got -1

OpenStudy (anonymous):

my mistake -3

OpenStudy (texaschic101):

yes....it is -3.....this is for the 3rd one

OpenStudy (anonymous):

wb the second? any idea ;-;

OpenStudy (texaschic101):

second one.. (1,2)...x1 = 1 and y1 = 2 (2,5)...x2 = 2 and y2 = 5 slope = (y2 - y1) / (x2 - x1) slope = (5 - 2) / (2 - 1) can you finish ?

OpenStudy (anonymous):

yes

OpenStudy (texaschic101):

so what did you get for the slope of the 2nd one ?

OpenStudy (anonymous):

3

OpenStudy (texaschic101):

correct :) you got this now...way to go

OpenStudy (anonymous):

OpenStudy (texaschic101):
