If its right let me know I think this is right

Formula - y = mx + b
Slope(m) = 1/2
Y-Intercept(b) = -5
To graph you always start with the y-intercept. So you would go down (since it is negative) 5 and then you would go up 1 ( since it is positive) and right 2 and you just keep going up 1 and right 2.
Hope this Helps and makes sense!!
I assume you mean the total number of jazz and classical songs combined is 28 songs?
3 times as many jazz as classical:
Means there is a ratio of 3 jazz to 1 classical, which means there are essentially 4 parts (3+1=4). So if we divide 28/4=7. This gives one part = number of classical songs, jazz is 3 parts so 7*3=21 jazz songs.
7 times as many rock as classical:
From above we know there are 7 classical songs. 7*7=49 rock songs.
Jazz=21 songs
Rock=49 songs
