Question 1204420


Find the x-intercept and y-intercept for 

{{{9x-8y=-72}}}

the {{{x}}}-intercept is at ({{{x}}},{{{0}}}), so set {{{y=0}}}

{{{9x-8*0=-72}}}

{{{9x=-72}}}

{{{x=-72/9}}}

{{{x=-8}}}

the {{{y}}}-intercept is at ({{{0}}},{{{y}}}), so set {{{x=0}}}

{{{9*0-8y=-72}}}

{{{-8y=-72}}}...both sides multiply by {{{-1}}}

{{{8y=72}}}

{{{y=72/8}}}

{{{y=9}}}


answer:

{{{x}}}-intercept: {{{-8}}}

{{{y}}}-intercept:{{{9}}}
