The table shows a proportional relationship between the number of stars roberto collects in a game and his total points. a row of values is missing in the table. which numbers of stars and total points could be used as the missing values in the table? choose 3 answers:

1) 20 stars; 30 points.

2) 28 stars, 42 points.

3) 38 stars, 57 points.

Step-by-step explanation:

Let  be "x" the numbers of stars Roberto collects and "y" his total points.

The proportional relationship has this form:

Where "k" is the constant of proportionality.

We can choose the point ) from the table, where:

Substituting these values into   and solving for "k", we get:

Knowing the value of "k", we determine that the  following Numbers of stars and the Total points could be used as the missing values in the table:

1) For :

2) For :

3) For :

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
