Question 899955
Ordered Pairs (x,y) 
(7, 5)
(4, 1) m = 4/3  {{{m =(y[1] - y[2])/(x[1] - x[2] )}}}
***Using point-slope form, {{{y - y[1] = m(x - x[1])}}} P(7,5)
y-5 = (4/3)(x-7)

the exercise is intended to Use following correctly.
It is not a guessing game
{{{m =(y[1] - y[2])/(x[1] - x[2] )}}}
and
{{{y - y[1] = m(x - x[1])}}}
