Answer:

Step-by-step explanation:

11.  Point (0,4) m=2

 y-y1 = m(x-x1)

 y - 4 = 2(x -0 )

  y-4 =2x

  y = 2x+4

12.  (3,5) and (9,3)

 m = (3-5) / (9-3)

 m = -2 / 6 = -1/3

y-y1 = m(x-x1)

y - 5 = (-1/3) (x - 3)

3y -15 = -(x-3)

3y = -x + 3 +15

3y = -x +18

13.  y = -x/3 + 6

14.  3x - 5y = 15

        -5y = -3x +15

         divide by -5 throughout

    y = (3/5)x - 3
