Question 124958

{{{3*x-6*y=9}}} Start with the given equation


Let's find the x-intercept


To find the x-intercept, let y=0 and solve for x:

{{{3*x-6*(0)=9}}} Plug in {{{y=0}}}


{{{3*x=9}}} Simplify


{{{x=9/3}}} Divide both sides by 3



{{{x=3}}} Reduce




So the x-intercept is *[Tex \Large \left(3,0\right)] (note: the x-intercept will always have a y-coordinate equal to zero)

{{{3*x-6*y=9}}} Start with the given equation


Now let's find the y-intercept


To find the y-intercept, let x=0 and solve for y:

{{{3*(0)-6*y=9}}} Plug in {{{x=0}}}


{{{6*y=9}}} Simplify


{{{x=9/-6}}} Divide both sides by -6




{{{y=-3/2}}} Reduce




So the y-intercept is *[Tex \Large \left(0,-\frac{3}{2}\right)] (note: the y-intercept will always have a x-coordinate equal to zero)


------------------------------------------


So we have these intercepts:

x-intercept: *[Tex \Large \left(3,0\right)]


y-intercept: *[Tex \Large \left(0,-\frac{3}{2}\right)]
