of the 400 songs in a playlist, 150 are pop songs. How many songs do you need to play on a shuffle setting to be sure you will hear a pop song

400-150=250 songs are not disco.

Therefore you must pick 250+1=251 to ensure you get at least 1 disco song

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
