*[invoke change_this_name10094 -1, -2, 4, 3]


Is the point ({{{3}}}, {{{1}}}) on this line? 
 
go to {{{y=(1)x + (-1)}}} or {{{y=x -1}}} and plug in {{{x=3}}} and {{{y=1}}}; if left side of equation is equal to  right side, than the point ({{{3}}}, {{{1}}}) is on this line

{{{1=3 -1}}}

{{{1=2}}} ...since {{{1<>2}}} the point ({{{3}}}, {{{1}}}) is NOT on this line
