Answer:

see below

Step-by-step explanation:

27) y = kx

18 = k(20)

18 = 20k

k = 0.9

28) y = kx

-9 = k(3)

-9 = 3k

k = -3

y = -3x

29a) y = kx

5 = k(1/3)

5 = 1/3k

k = 15

y = 15x

29b) y = 15x

y = 15(-2)

y = -30

Answer:

With Two points is enough to describe this graph

$\left[\begin{array}{ccc}\frac{4}{6} &0\\0&-4\\\end{array}\right]$

Step-by-step explanation:

Interception with Y axis (y=0), thus we have the following equation:

$0=6*x+4$

$x=4/6$

The point for this is (4/6 , 0)

Interception with x axis (x=0), thus we have the following equation:

$Y=4*0-4$

$y=-4$

The point for this is (0, -4)
