Answer:
y = - 2x + 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (3, 7) and (x₂, y₂ ) = (5, 3)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 7), then
7 = - 6 + c ⇒ c = 7 + 6 = 13
y = - 2x + 13 ← equation of line
Length in units:
Use phytogoras theorem or measure it by a ruler if your using a graph paper
AB = 5.65 units
AC = 5.83 units
CB = 1.41 units
Perimeter =5.65 + 5.83 + 1.41 = 12.89 units
Area = 1/2 * 1.41 * 5.65 = 3.98units
According to the commutative property of multiplication, changing the order of components has no effect on the product. The correct option is B.
<h3>What is the commutative property of multiplication?</h3>
According to the commutative property of multiplication, changing the order of components has no effect on the product.
For example: 4 × 8 = 8 × 4 = 32
The equation that correctly shows the Commutative Property of Multiplication is,
5 × 1 3 = 5 × 1 3
Hence, the correct option is B.

Answer:
the median is 15
Explanation:
you can find the median by arranging the numbers from smallest to largest and finding the number in the middle.
5 14 15 <u>15</u> 16 17 18
in this case, the number in the middle is 15 so the median for this data set is 15.
i hope this helps! :D
The expression that is equivalent to the given expression is -4x^-5
<h3>How to determine which expression is equivalent to the given expression?</h3>
The expression is given as:

Rewrite properly as
-4x^-5x^0
Express as products
-4x^-5 * x^0
The value of x^0 is 1
So, we have:
-4x^-5 * 1
Evaluate the product
-4x^-5
Hence, the expression that is equivalent to the given expression is -4x^-5
