Help on this this is the last one promise!!

6) check picture

a) all three lines are parellel and have the same slope. the only difference is that they are translated on different points on the x-axis.

not sure about the rest sorry :(

Shewannameetcarti answered the numbers 6 and 7 perfectly!

I'll just add on with number 8.

a. 4 + 12x

  (This is because the first figure starts with 4 toothpicks, and each time there

   are 12 more toothpicks in the pattern.)

b. *graphs are attached; both are the same equation, one is just zoomed out

c. Using the graph, the number of toothpicks in figure 7 is 88 toothpicks.

   Substitute 7 for x: 4 + 12(7) = 88

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
