Question 514729


<h4>x-intercept</h4>

To find the x-intercept, plug in {{{y=0}}} and solve for x



{{{3x-5y=-15}}} Start with the given equation.



{{{3x-5(0)=-15}}} Plug in {{{y=0}}}.



{{{3x-0=-15}}} Multiply {{{-5}}} and 0 to get 0.



{{{3x=-15}}} Simplify.



{{{x=(-15)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}.



{{{x=-5}}} Reduce.



So the x-intercept is *[Tex \LARGE \left(-5,0\right)].



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



<h4>y-intercept</h4>

To find the y-intercept, plug in {{{x=0}}} and solve for y



{{{3x-5y=-15}}} Start with the given equation.



{{{3(0)-5y=-15}}} Plug in {{{x=0}}}.



{{{0-5y=-15}}} Multiply {{{3}}} and 0 to get 0.



{{{-5y=-15}}} Simplify.



{{{y=(-15)/(-5)}}} Divide both sides by {{{-5}}} to isolate {{{y}}}.



{{{y=3}}} Reduce.



So the y-intercept is *[Tex \LARGE \left(0,3\right)].



Now let's plot the points *[Tex \LARGE \left(-5,0\right)] and *[Tex \LARGE \left(0,3\right)] which are the x and y intercepts respectively.



{{{drawing(500, 500, -10,10,-10,10,
grid(0),
graph(500, 500, -10,10,-10,10,0)
circle(-5,0,0.03),circle(-5,0,0.05),circle(-5,0,0.08),circle(-5,0,0.10),circle(-5,0,0.12),
circle(0,3,0.03),circle(0,3,0.05),circle(0,3,0.08),circle(0,3,0.10),circle(0,3,0.12)
)}}}



Now draw a straight line through the plotted points to graph {{{3x-5y=-15}}}.
