Answer:
a) ok, heres what u graph, and ur ordered pairs
graph the following points:
(0,0) (1,5) (2,10) (3,15) (4,20) (5,25) (6,30) (7,35), and so on
b) One of the ordered pairs I can use is (1,5). This is beacuse the ordered pair explains that for every video game (x), 5 will be the cost (y).
You can answer this problem using the midpoint formula, but we can work out the 4th vertex by just logically thinking it through by first drawing out the rhombus on an x-y coordinate plane. I wrote the answer out on paper since it is easier than typing. Let me know if you have any questions.
we know that
the two triangles in the figure are similar, because they have three equal angles
therefore
The ratio of the corresponding sides are equal
![\frac{x}{8}= \frac{18}{48} \\ \\x=(8*18)/48 \\ \\x=3\ units](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B8%7D%3D%20%5Cfrac%7B18%7D%7B48%7D%20%5C%5C%20%5C%5Cx%3D%288%2A18%29%2F48%20%5C%5C%20%5C%5Cx%3D3%5C%20units)
therefore
<u>the answer is the option C</u>
