first find y-intercept
y-intercept where line cross y-axis that point is y-intercept
loook at the graph and tell me what is y-intercept
OpenStudy (anonymous):
is it 4
Nnesha (nnesha):
yes right now find take two points from the graph to find slope
Nnesha (nnesha):
and remember
if line increasing then slope should be positive
and if line decreasing then slope should be negative

is it -5
OpenStudy (anonymous):
(-5,4)
Nnesha (nnesha):
nope slope is not -5
and why did you write that in order pair
slope intercept e equation is y = mx + b
OpenStudy (anonymous):
4x+-5
Nnesha (nnesha):
nope
y = mx + b where m is slope which is always with x
and b is y-intercept
so u just found out that y-intercept is 4

and slope is not -5
OpenStudy (anonymous):
is it 3
OpenStudy (anonymous):
or 4
Nnesha (nnesha):
how did you get that ??
Nnesha (nnesha):
|dw:1424329481672:dw|use this two point to find slope
