Intercept form of plane equation :
\[\dfrac{x}{a} + \dfrac{y}{b} + \dfrac{z}{c}=1\]
OpenStudy (rational):
it is easy to eyeball intercepts from the given diagram
OpenStudy (nightmarenight):
I'm confused @rational
OpenStudy (rational):
Look at the given diagram
where does the plane cut x axis ?

1
OpenStudy (nightmarenight):
oh
OpenStudy (rational):
Yes so x intercept = a = 1
similarly b = 2, c = 3
OpenStudy (rational):
plug them in the equation :
\[\dfrac{x}{1} + \dfrac{y}{2}+\dfrac{z}{3}=1\]

multiply 6 through out to make it look nice
OpenStudy (nightmarenight):
\[\frac{ x }{ 6 } + \frac{ y }{ 12 } + \frac{ z }{ 18 } \]
OpenStudy (nightmarenight):
@rational ^^^
OpenStudy (kittiwitti1):
I think he meant make the denominators all 6.
OpenStudy (kittiwitti1):
Like:\[\frac{x\times 6}{1\times 6}+\frac{y\times 3}{2\times 3}+\frac{z\times 2}{3\times 2}=\frac{1\times 6}{1\times 6}\]
