Answer:
x+y=45, (5,40) and ( 25,20)
Step-by-step explanation:
Here we are given the information that Gian was given 45 mins to spend on computer after dinner. Out of those 45 mins , he can either play games of watch videos.
Therefore If the time for which he watches videos is x and that of the time he spend playing game is y , there sum must be equal to 45 mins.
Hence our equation in terms of x andy will be
[tex]x+y=45[/tex]
Now let us see the graph part.
Here we see that the graph is plot on xy plane where x is taken as time taken in watching videos and y as playing games
i) on Monday , he watch 5 minutes in watching videos
Hence x=5 , we put x=5 in x+y=45 and solve it for y
5+y=45
subtracting 5 from both sides
5+y-5=45-5
y=40
Hence he spend 40 mins on playing games.
So we plot Point (5,40) for monday.
i) on Tuesday , he watch 25 minutes in watching videos
Hence x=25 , we put x=25 in x+y=45 and solve it for y
25+y=45
subtracting 25 from both sides
25+y-25=45-25
y=20
Hence he spend 20 mins on playing games.
So we plot Point (25,20) for Tuesday.
