Question 63295
(6,y) (3/2,4/5) when m=2/3
The slope formula is {{{highlight(m=(y2-y1)/(x2-x1))}}}
(x1,y1)=(6,y) and (x2,y2)=(3/2,4/5)
{{{2/3=(4/5-y)/(3/2-6)}}}
{{{(2/3)(3/2-6)=(4/5-y)*cross((3/2-6))/cross((3/2-6))}}}
{{{6/6-12/3=4/5-y}}}
{{{1-4=4/5-y}}}
{{{-3=4/5-y}}}
{{{-3-4/5=-4/5+4/5-y}}}
{{{-15/5-4/5=-y}}}
{{{-19/5=-y}}}
{{{-1(-19/5)=-1(-y)}}}
{{{19/5=y}}}
Happy Calculating!!!!
