Question 184650
I can use the general formula
{{{m = (y - y[1]) / (x  - x[1])}}}
given:
The point (-2,-1)
{{{x[1] = -2}}}
{{{y[1] = -1}}}
{{{m = 13/19}}}
-----------------
{{{13/19 = (y - (-1)) / (x  - (-2))}}}
{{{13/19 = (y + 1) / (x + 2)}}}
Multiply both sides by {{{19*(x + 2)}}}
{{{13*(x + 2) = 19*(y + 1)}}}
{{{13x + 26 = 19y + 19}}}
{{{13x - 19y = -7}}} answer
