Question 134405


{{{2*x-4*y=8}}} Start with the given equation


Let's find the x-intercept


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

{{{2*x-4*(0)=8}}} Plug in {{{y=0}}}


{{{2*x=8}}} Simplify


{{{x=8/2}}} Divide both sides by 2



{{{x=4}}} Reduce




So the x-intercept is *[Tex \Large \left(4,0\right)] (note: the x-intercept will always have a y-coordinate equal to zero)

{{{2*x-4*y=8}}} Start with the given equation


Now let's find the y-intercept


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

{{{2*(0)-4*y=8}}} Plug in {{{x=0}}}


{{{4*y=8}}} Simplify


{{{x=8/-4}}} Divide both sides by -4




{{{y=-2}}} Reduce




So the y-intercept is *[Tex \Large \left(0,-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(4,0\right)]


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




Now plot the two points *[Tex \Large \left(4,0\right)] and *[Tex \Large \left(0,-2\right)] 


{{{drawing(500, 500, -6, 6, -4, 4,
graph(500, 500, -6, 6, -4, 4,0),
circle(4,0,0.0666666666666667),
circle(4,0,0.0966666666666667),

circle(0,-2,0.0666666666666667),
circle(0,-2,0.0966666666666667)


)}}}



Now draw a line through the two points to graph {{{2*x-4*y=8}}}

{{{drawing(500, 500, -6, 6, -4, 4,
graph(500, 500, -6, 6, -4, 4,(8-2*x)/-4),
circle(4,0,0.0666666666666667),
circle(4,0,0.0966666666666667),

circle(0,-2,0.0666666666666667),
circle(0,-2,0.0966666666666667)


)}}} graph of {{{2*x-4*y=8}}} through the points *[Tex \Large \left(4,0\right)] and *[Tex \Large \left(0,-2\right)]
