Which graph appears to show a proportional relationship between x and y?​

Answer:

the answer is "A"

Step-by-step explanation:

they way to tell is a proportional line always crosses in the (0,0) if not it is not a proportional line

Graph A appears to show a proportional relationship between x and y. Because it is a straight line across the origin.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

A line graph is a type of graph where the data points are connected by segments of straight lines. A straight line is a combination of endless points joined on both sides of the point.

A proportionate relationship's graph is always a straight line with a starting point of (0, 0). The graph is created by calculating a second point and then connecting them with a straight line.

Thus, graph A appears to show a proportional relationship between x and y. Because it is a straight line across the origin.

Regression Project: Find the Profit Model

Annual Widget Production x (widgets) Annual Total Cost c($)
10 609
20 1105
30 1523
40 2150
50 2603
60 3121
70 3672
80 4103
90 4601
100 5214
Recall that profit can be computed in terms of revenue and cost. Assume that the annual widget sales match the annual widget demand and annual widget production. Construct a model for profit using the models for revenue and cost that you found in the Revenue and Cost sections. Find the model for profit P ( x ), where P ( x ) is the total annual profit in dollars for x widgets sold, and write it as P ( x ) = a x 2 + b x + c. Note: You are using the fact that P ( x ) = R ( x ) − C ( x ), not creating a table of data.

Quadrilateral EFGH was dilated by a scale factor of 2 from the center (1, 0) to create E'F'G'H'. Which characteristic of dilations compares segment F'H' to segment FH?

A: A segment that passes through the center of dilation in the pre-image continues to pass through the center of dilation in the image.

B: A segment that does not pass through the center of dilation in the pre-image is parallel to its corresponding segment in the image.

C: A segment in the image has the same length as its corresponding segment in the pre-image.

D: A segment that does not pass through the center of dilation in the pre-image is perpendicular to its corresponding segment in the image.
