Question 91077


{{{2*x-5*y=10}}} 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-5*(0)=10}}} Plug in {{{y=0}}}


{{{2*x=10}}} Simplify


{{{x=10/2}}} Divide both sides by 2


{{{x=5}}} Reduce


So the x-intercept is ({{{5}}},0) (note: the x-intercept will always have a y-coordinate equal to zero)

{{{2*x-5*y=10}}} Start with the given equation


Now let's find the x-intercept


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

{{{2*(0)-5*y=10}}} Plug in {{{x=0}}}


{{{5*y=10}}} Simplify


{{{x=10/-5}}} Divide both sides by -5


{{{y=-2}}} Reduce


So the y-intercept is (0,{{{-2}}}) (note: the y-intercept will always have a x-coordinate equal to zero)


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


So we have these intercepts:

x-intercept: ({{{5}}},0)


y-intercept: (0,{{{-2}}})




Now plot the two points ({{{5}}},0) and (0,{{{-2}}}) 


{{{drawing(500, 500, -7, 7, -4, 4,
graph(500, 500, -7, 7, -4, 4,0),
circle(5,0,0.0777777777777778),
circle(5,0,0.107777777777778),

circle(0,-2,0.0777777777777778),
circle(0,-2,0.107777777777778)


)}}}



Now draw a line through them

{{{drawing(500, 500, -7, 7, -4, 4,
graph(500, 500, -7, 7, -4, 4,(10-2*x)/-5),

circle(5,0,0.107777777777778),

circle(0,-2,0.0777777777777778),
circle(0,-2,0.107777777777778)


)}}} graph of {{{2*x-5*y=10}}} through the points ({{{5}}},0) and (0,{{{-2}}})
