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)

<u>y+3=-1/3(x-9)</u>

6.

3h--> $75

1h--> $15

a)

Standard form: Ax + By = C

m(slope)=15

y=15x

y-15x=0

-15x+y=0

<u>15x-y=0</u>

b)

<u>10 hours of work---> $150</u>

In order for them to work the same amount of time, you would have to make Lucas work for five hours (so he could have the same minimum time as Jonathan). So multiply Lucas's 30 minutes by five, and that equals a total of 2 hours and 30 minutes. So when Jonathan works for five hours he plays for three hours, but when Lucas works for 5 hours he only plays for 2 hours and 30 minutes. So Jonathan spends more time playing video games.

mestny [16]

Answer:

Ok so you have to find how much it goes up at a time. So the first one is 1,5. Then multiply both by 5 to get 5,25. That is your answer then. The graph will have 5 on the bottom and 25 on the side.
