** correct answer(letter) with small-and easy to understand explination **

There is no points of intersection

Step-by-step explanation:

∵ The slope of line u = 4 - (-8)/5 - 9 = 12/-4 = -3

∴ Its equation is ⇒ y = -3x + c ⇒ use point (5 , 4) to get c

                                4 = -3(5) + c ⇒ c = 4 + 15 = 19

∴ The equation of u is ⇒y = -3x + 19

∵ The slope of line v = -7 - 2/7 - 4 = -9/3 = -3

∴ Its equation is ⇒ y = -3x + c ⇒ use point (4 , 2) to get c

                               2 = -3(4) + c ⇒ c = 2 + 12 = 14

∴ The equation of v is ⇒y = -3x + 14

∵ The slopes of them are equal and their y-intercepted are not equal

∴ Line u is parallel to line v

∴ There is no point of intersection
