1) See figure attached
2)
a) 
And if we replace we got:

b) 
And if we replace we got:

Step-by-step explanation:
Part 1
We can see the plot in the figure attached.
Part 2
a)
For this case we have two points 
And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:

And if we replace we got:

b)
Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:

And if we replace we got:

Answer:
write 4/27 as the product of a prime raised to a power
Slope is defined as the rate of change, in this case the change in y with respect to x. In standard form for a binomial linear equation, y = mx + b. The constants m and b are the slope and intercept, respectively. For your equation, the slope is -2 and the intercept is 0. The domain (possible values of x) for this graph is (-∞, ∞) and the range (possible values of y) is also (-∞, ∞).
Answer:
You will pay $332.50 for a item with original price of $475 when discounted 30%
meaning the discount is $142.50
Step-by-step explanation:
if you buy an item at $475 with 30% discount, you will pay 475 - 142.5 = 332.5 dollars.
