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?

@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

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 ?
