Answer:
y=mx+c, m represents the slope while c the y-intercept. (never forget that)
The 'V' one, because it's just a linear x = y with no negative y values, so it goes back up into a 'V'.
Add the ratios: 3 + 7 + 5 = 15
Divide total songs by the sum:
60 / 15 = 4
Now multiply each ratio by that:
3 x 4 = 12
7 x 4 = 28
5 x 4 = 20
Answer: trap = 12, r&b = 28, reggaeton = 20
After multiplying by the stated coefficients and adding, the equation obtained is:
8y - 7.5y = 0
y = 0
x = 4
Because the two equations formed were independent, they had one solution.
