Question 1131650


Find the x- and y-intercepts of the line.

{{{5x + 4y = 20}}}

to find x-intercept, set {{{y=0}}} 

{{{5x + 4*0 = 20}}}

{{{5x = 20}}}

{{{x = 20/5}}}

{{{x = 4}}}
   	
({{{x}}}, {{{y}}}) = ({{{4}}}, {{{0}}})

  
  

to find y-intercept, set {{{x=0}}} 

{{{5*0 + 4y = 20}}}
	
{{{ 4y = 20}}}

{{{ y = 20/4}}}

{{{ y = 5}}}

({{{x}}}, {{{y}}}) = ({{{0}}}, {{{5}}})
