Well, the second point's coordinates are (6,12)

The first point's coordinates are (3,21)

The slope intercept form would be (12-21) / (6-3) which is -3.

The point slope form would be y - 21 = -3(x - 3)




His delivery time decreased by 3 minutes.



Hope this helps!

Hi There!

Slope Intercept Form: y = mx + b

Point Slope Form: y - y1 = m(x - x1)


Part A:

Find the slope:

y2 - y1/x2 - x1 = m

12 - 21/3 - 6 = -9/-3 = 3

Slope = 3

Slope Intercept Form: y = 3x + 29

Point Slope Form: y - 21 = 3(x - 3)


Part B:

When scott started on Day 1 he was delivering packages every 29 minutes. By the time he reached Day 10 was delivering packages every 2 minutes. Im not entirely sure about this part.


Hope This helps :)

Find the polynomial function
laiz [17]

Answer:

y = 2x³ +x² -3x +6

Step-by-step explanation:

The polynomial correlation function of a graphing calculator can work with the table of function values to give you the equation. (See attached)

_____

If you want to solve this by hand, you can write the equations for the unknown coefficients in the polynomial function, then solve those. First of all, notice that you are given the y-intercept, (0, 6), so you know one of the coefficients already. That leaves a system of 3 equations in 3 unknowns that need to be solved.

___

<em>Writing the equations</em>

... ax³ +bx² +cx +6 = y . . . . the generic linear equation in a, b, c that you're writing

For x = -1:

... -a +b -c +6 = 8

For x = 1

... a + b + c + 6 = 6

For x = 2

... 8a +4b +2c +6 = 20

In augmented matrix terms, this set of linear equations looks like ...

\left[\begin{array}{ccc|c}-1&1&-1&2\\1&1&1&0\\8&4&2&14\end{array}\right]

___

<em>Solving the equations</em>

There are a number of ways to solve these. Again, a graphing calculator often has solution functions, such as reducing a matrix to row-echelon form, that will solve this in a keystroke or two.

If you add the first two equations, you get ...

... 2b = 2 ⇒ b = 1

Substituting that into the first equation allows you to simplify it to ...

... -a -c = 1

Dividing the third equation by 2 (and substituting for b) makes it ...

... 4a +c = 5

Adding these equations gives ...

... 3a = 6 ⇒ a = 2

Then ...

... c = -a -1 = -2 -1 = -3

And our polynomial function is ...

... y = 2x³ +x² -3x +6
