Answer:


Slope = (2)/(3)

Explanation:

Use the slope formula:

Slope (m) =
(y_2 - y_1)/(x_2 - x_1)

Let:


(x_1 , y_1) = (6 , -9)\\(x_2 , y_2) = (27 , 5)

Plug in the corresponding numbers to the corresponding terms:

m =
(y_2 - y_1)/(x_2 - x_1) = ((5) - (-9))/((27) - (6)) = (5 + 9)/(27 - 6) = (14)/(21)

Remember to simplify. Divide common factors from both the numerator and denominator:


( ((14)/(21)) )/((7)/(7) ) = ((14)/(7) )/((21)/(7) ) = (2)/(3)


Slope = (2)/(3)
