1 answer:
Vadim26 [7]3 years ago

Answer:

1) See Attachment.

2) The slope is -2/3.

3) The y-intercept is y=2.

Step-by-step explanation:

We have the two points (6, -2) and (-3, 4) and we know that they are on the same line.

Part 1)

In order to graph a line given two points, we simply need to plot those two points and then draw a line through them.

Please see the attachment.

We would plot (6, -2) and (-3, 4). Then, use a straightedge to connect the two points.

Part 2)

To find the slope, we can use the slope formula.

The slope formula for the slope between any two points is:

m=\frac{y_2-y_1}{x_2-x_1}

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let‘s let (6, -2) be (x₁, y₁) And (-3, 4) be (x₂, y₂). Substituting them into the slope formula yields:

m=\frac{4-(-2)}{-3-6}

Evaluate:

m=\frac{6}{-9}=-2/3

So, the slope is -2/3.

We can confirm this using our graph. Remember that the slope measures rise over run.

We are going <em>down by 2</em> for every <em>3 to the right</em>.

Part 3)

The y-intercept is where the graph crosses the y-axis.

From the graph, we can see that the graph crosses the y-axis at (0, 2).

Therefore, the y-intercept is y=2.

Consumer complaints are frequently reported to the Better Business Bureau. Industries with the most complaints to the Better Bus
Licemer1 [7]

Answer:

Let the complaints by Industry be CbI

CbI               Frequency

Bank            26

Cable           44

Car               42

Cell               60

Collection     28

b) Percentages

CbI               percentage (%)

Bank              13

Cable            22

Car                21

Cell               30

Collection     14

c) The industry with the highest number of complaints is the Cell Industry.

d) The Bar Chart is attached to this solution. It was constructed in the Ms Excel suite.

Step-by-step explanation:

a) The frequencies are simply the number of times each industry sector sent in a complaint. So, it's straight forward to present.

b) The percentage for each industry is done in comparison to the the total amount of complaints received.

Percentage for each industry = 100% × (Number of complaints from that industry)/(Total number of complaints)

Total amount of complaints received = 200

For Bank industry,

Percentage = 100% × (26/200) = 13%

For the Cable Industry,

Percentage = 100% × (44/200) = 22%

For Car industry,

Percentage = 100% × (42/200) = 21%

For Cell industry,

Percentage = 100% × (60/200) = 30%

For Collection industry,

Percentage = 100% × (28/200) = 14%

c) The industry with the highest number of complaints is the one with the highest frequency and percentage, and that is the Cell Industry.

d) The Bar Chart is attached to this solution. It was constructed in the Ms Excel suite.
