the slope is calculated from the change in y/change in x between 2 points
read the 2 points from the axes:
x1=0
y1= ?
x2= ?
y2=0
OpenStudy (mrnood):
if you're not going to reply I'm out in a couple of mins...
OpenStudy (pphalke):
I don't know how to find the points I know 0 but I don't know th other

(0,3) and (0,-4)

well close
the second is correct - but the first is the wrong way round - always read the x first (I gave a hint on my drawing)
OpenStudy (pphalke):
(3,0)
OpenStudy (mrnood):
OOOPS sorry - my mistake
(0,3) is correct but the OTHER one is (-4,0)
so
x1= 0
y1= 3
x2 = -4
y2 = 0
the slope m is calculated from
\[m= \frac{ y2-y1 }{ x2-x1}\]
so substitute the numbers into that equation to find m
OpenStudy (pphalke):
-3/-4

OK
But both top and bottom are negative
so write this more simply - and you have your correct answer...
