{{{y=-2x+5}}} 

{{{y=-2x-5}}}


*[invoke solve_by_graphing 2, 1, 5, 2, 1, -5]


the distance between them is {{{5}}}; from the {{{x-intercept}}} of first line to {{{x-intercept}}} of second line

the {{{x-intercept}}} of first line is

{{{0=-2x+5}}}.......=>......{{{2x=5}}}.....=>......{{{x=5/2=2.5}}}

the {{{x-intercept}}} point is ({{{2.5}}},{{{0}}})

the {{{x-intercept}}} of second line is

{{{0=-2x-5}}}.......=>......{{{2x=-5}}}.....=>......{{{x=-5/2=-2.5}}}

the {{{x-intercept}}} point is ({{{-2.5}}},{{{0}}})


the distance between these two points is the distance between two given lines:
