Question 5458
I think you missed this one.  


First find the slope, which is m= {{{(y[2] - y[1])/(x[2] - x[1]) }}}
m = {{{ (4-7) /(2-(-3))= -3/5}}}

{{{y-7= (-3/5) * (x+3)}}}
{{{y - 7 = (-3/5)*x -3/5*3}}}
{{{y - 7 =(-3/5)x - 9/5}}}
{{{y = (-3/5) x -9/5 + 7}}}
{{{y = (-3/5)x + 26/5}}}


Check by substituting x = 2, and see if you get y = 4!  It works!!
