what is the equation in point-slope form of a line that passes through the points (7, -8) and (-4, 6)?
Marizza181 [45]

<u>Answer</u>

y - 6 = -14/11(x + 4)


<u>Explanation</u>

slope = (change in y)/ (change in x)

          = (6 - -8) / (-4 - 7)

         = 14/-11

         = -14/11

Equation

-14/11 = y - 6)/(x - -4)

-14/11 = (y - 6)/(x + 4)

-14(x + 4) = 11(y - 6)

y - 6 = -14/11(x + 4)


The answer is the third one.
