Question 651680
{{{y=-5x+1 }}}...here you have a linear function; so, the graph will be a line

to graph a line you need two points to plot on the Cartesian coordinate system

easiest way to find these points is to set {{{x=0}}} and find {{{y}}} which will be {{{y-intercept}}}, and to set {{{y=0}}} and find {{{x}}} which will be {{{x-intercept}}}

{{{y=-5x+1 }}}...if {{{x=0}}}, {{{y}}} will be:

{{{y=-5*0+1 }}}

{{{y=1 }}}

so, {{{y-intercept}}} is at ({{{0}}},{{{1}}})


{{{y=-5x+1 }}}...if {{{y=0}}}, {{{x}}} will be:

{{{0=-5x+1 }}}

{{{5x=1 }}}

{{{x=1/5 }}}

so, {{{x-intercept}}} is at ({{{1/5}}},{{{0}}})

now you are ready to plot these points on the Cartesian coordinate system and draw a line through

{{{ graph( 600, 600, -5, 5, -5, 10, -5x+1) }}}
