\[\frac{ x }{ 2 } + \frac{ y }{ 3 } - 2 = 0 \]
OpenStudy (rane):
find the y intercept and gradient
OpenStudy (skullpatrol):
Any ideas?
OpenStudy (anonymous):
to find y-intercept put x = 0 and solve for y
0/2 + y/3 - 2 = 0
0+ y/3 - 2 = 0
y/3 = 2
y = 6 ----> y-intercept

@rizwan_uet let the student ask questions please :-)

now write x/2 + y/3 - 2 = 0 interms of x first and compare it with y = mx + b
OpenStudy (rane):
@rizwan_uet don't we have to re-arrange the equation in to \[y= mx + c \], before finding anything ?
OpenStudy (anonymous):
yes you have to rearrange it to y = mx+ b form
OpenStudy (skullpatrol):
Good question @RANE
OpenStudy (anonymous):
and the value associated with x will be the gradient

is the value of m = 3?
OpenStudy (anonymous):
how you got this??
OpenStudy (rane):
\[3x + 2y - 12 = 0,
-2y = 3x-12 \]
OpenStudy (anonymous):
now divide both sides by -2 to get the form y = mx+b
OpenStudy (skullpatrol):
Good job, but you're not finished...

so is it \[ m = \frac{ 3 }{ -2 }\]
OpenStudy (anonymous):
exactly its -3/2
OpenStudy (rane):
thank you
