Answer:

4. y+3=-1/3(x-9) 6a. 15x-y=0  6b. $150

Step-by-step explanation:

4.

Point slope form formula: y-y1=m(x-x1)

Includes origin and point (9,-3)

m= y2-y1/x2-x1

-3-0/9-0= -3/9=-1/3

slope= -1/3

Since we already have the point (9,-3),

enter the information above into the point slope form formula.

y-(-3)=-1/3(x-9)

y+3=-1/3(x-9)

6.

3h--> $75

1h--> $15

a)

Standard form: Ax + By = C

m(slope)=15

y=15x

y-15x=0

-15x+y=0

15x-y=0

b)

10 hours of work---> $150
