Step-by-step explanation:

7) The equation of the straight line passing through the ordered pair (-3,5) and (3,-5) is given by

⇒ -3(y - 5) = 5(x + 3)

⇒ -3y + 15 = 5x + 15

⇒ 5x + 3y = 0

⇒ (Answer)

8) The equation of the straight line passing through the ordered pair (5,7) and (11,16) is given by

⇒ 2(y - 7) = 3(x - 5)

⇒ 2y - 14 = 3x - 15

⇒ 3x - 2y - 1 = 0

⇒ (Answer)
