Kruka [31]3 years ago
8 0

Answer: 5/1

Step-by-step explanation:

After 5 hours, it would be at zero.  And 100 divided by 4, is 20.   Meaning that the slope is 5/1, or 5.

Point WW is located at (6,4)(6,4) on the coordinate plane. Point WW is reflected over the yy-axis to create point W'W ′ . Point
yKpoI14uk [10]

Using translation concepts, the ordered pair that describes the location of W'' is: W''(-6,-4).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a reflection over the y-axis is:

(x,y) -> (-x,y).

Hence:

W'(-6,4).

The rule for a reflection over the x-axis is:

(x,y) -> (x, -y).

Hence:

W''(-6,-4).

For 9 and 9A, find the slope of the line​
djverab [1.8K]

For this case we have that by definition, the slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Where:

(x_ {1}, y_ {1}) and (x_ {2}, y_ {2}) are two points through which the line passes.

Question 1:

According to the image, we have the following points:

(x_ {1}, y_ {1}) :( 2, -6)\\(x_ {2}, y_ {2}): (- 6,5)

Substituting we have:

m = \frac {5 - (- 6)} {- 6-2} = \frac {5 + 6} {- 8} = \frac {11} {- 8} = - \frac {11} {8}

Thus, the slope is: - \frac {11} {8}

Question 2:

According to the image, the line goes through the following points:

(x_ {1}, y_ {1}): (- 1,2)\\(x_ {2}, y_ {2}) :( 2, -2)

Substituting we have:

m = \frac {-2-2} {2 - (- 1)} = \frac {-4} {2 + 1} = \frac {-4} {3} = - \frac {4} {3}

Thus, the slope is: - \frac {4} {3}

Answer:

Slope 1: - \frac {11} {8}

Slope 2:- \frac {4} {3}
