Question

Please answer this correctly, just a few simple problems.

Answer 1

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
