Part A:

The parametric equations x=x_1+(x_2-x_1)t and y=y_1+(y_2-y_1)t where 0\leq t\leq1 describes the line segment that joins the points (x_1,\ y_1) and (x_2,\ y_2).

The parameterization of the line joining points A(1, 1) and B(5, 3) are given by substituting x_1=1,\ \ y_1=1,\ \ x_2=5,\ \ y_2=3.

Thus, we have

x = 1 + (5 - 1)t = 1 + 4t
y = 1 + (3 - 1)t = 1 + 2t

Therefore, the parameterization of line joining points A(1, 1) and B(5, 3) are x = 1 + 4t and y = 1 + 2t.



Part B:

The parametric equations x=x_1+(x_2-x_1)t and y=y_1+(y_2-y_1)t where 0\leq t\leq1 describes the line segment that joins the points (x_1,\ y_1) and (x_2,\ y_2).

The parameterization of the line joining points B(5, 3) and C(1, 7) are given by substituting x_1=5,\ \ 
y_1=3,\ \ x_2=1,\ \ y_2=7.

Thus, we have

x = 5 + (1 - 5)t = 5 - 4t
y = 3 + (7 - 3)t = 3 + 4t

Therefore, the parameterization of line joining points B(5, 3) and C(1, 7) are x = 5 - 4t and y = 3 + 4t.



Part C:

The parametric equations x=x_1+(x_2-x_1)t and y=y_1+(y_2-y_1)t where 0\leq t\leq1 describes the line segment that joins the points (x_1,\ y_1) and (x_2,\ y_2).

The parameterization of the line joining points C(1, 7) and A(1, 1) are given by substituting x_1=1,\ \ 
y_1=7,\ \ x_2=1,\ \ y_2=1.

Thus, we have

x = 1 + (1 - 1)t = 1
y = 7 + (1 - 7)t = 7 - 6t

Therefore, the parameterization of line joining points A(1, 1) and B(5, 3) are x = 1 and y = 7 - 6t.

Question: The meaning of four consecutive even numbers is 15.
nasty-shy [4]
First, a bit of housekeeping:

<span>The meaning of four consecutive even numbers is 15.  Wouldn't that be "mean," not meaning?  Very different concepts!

The greatest of these numbers is _______ a^1

"a^1" means "a to the first power.  There are no powers in this problem statement.  Perhaps you meant just "a" or "a_1" or a(1).


The least of these numbers is ______a^2.
No powers in this problem statement.  Perhaps you meant a_2 or a(2)


In this problem you have four numbers.  All are even, and there's a spacing of 2 units between each pair of numbers (consecutive even).

The mean, or arithmetic average, of these numbers is (a+b+c+d) / 4, where a, b, c and d represent the four consecutive even numbers.  Here this mean is 15.  The mean is most likely positioned between b anc c.


So here's what we have:  a+b+c+d
                                         ------------- = 15
                                                 4

This is equivalent to a+b+c+d = 60.

Since the numbers a, b, c and d are consecutive even integers, let's try this:

a + (a+2) + (a+4) + (a+6) = 60.    Then 4a+2+4+6=60, or 4a = 48, or a=12.

Then a=12, b=14, c=16 and d=18.  Note how (12+14+16+18) / 4 = 15, which is the given mean.

We could also type, "a(1)=12, a(2)=14, a(3) = 16, and a(4) = 18.
