Question 121025
{{{(y-1)/(x+3)=-3/4}}}......cross multiply

{{{(y-1)4 =(x+3)(-3)}}}......

{{{4y-4 = -3x-9}}}......

{{{4y = -3x -9 + 4}}}......

{{{4y = -3x - 5 }}}.........divide both sides by {{{4}}}

{{{4y/4 = -3x/4 - 5/4 }}}......simplify

{{{cross(4)y/cross(4) = -(3/4)x - 5/4 }}}......

{{{y = -(3/4)x - 5/4 }}}......
