Question 412430
the formula is
{{{(y - (-3)) / (x - (-2)) = (5 - (-3)) / (-4 - (-2))}}}
{{{(y + 3) / (x + 2) = (5 + 3) / (-4 + 2)}}}
{{{(y + 3) / (x + 2) = -4}}}
{{{y + 3 = -4*(x + 2)}}}
{{{y + 3 = -4x - 8}}}
{{{y = -4x - 11}}} answer
check answer:
Plug each of the points back into equation:
(-4,5)
{{{y = -4x - 11}}}
{{{5 = -4*(-4) - 11}}}
{{{5 = 16 - 11}}}
{{{5 = 5}}}
OK
