Answer:
D
Step-by-step explanation:
As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.
Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)
The option A is incorrect due to the same problem for the point (8,7)

Answer:
Step-by-step explanation:
Let's call lifeguarding L and car washing W. In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.
If she works 10 hours, that is the number of hours worked between both jobs. Therefore, the equation for the NUMBER of hours worked is
L + W = 10.
If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W. The MONEY she earned together by doing both those jobs is
13L + 12W = 124
There you go!
(Y,X) = (72,8)
I think this is the right answer it has been a while since I had math sorry. Hope this helps
