Out of the top 20 video games sold, how many more music games were there than
racer games?

if any of the answers are wrong please do correct me thank you.

Hello from MrBillDoesMath!

Not equation exists as the points o not lie on a line

Discussion:

Compute slope for first and second points:

m = (diff of y)/(diff of x) = (150-100)/(2-1) = 50/1 = 50

Slope for second and third points:

m = (250 -150)/(3-2) = 100/1 = 100

As 50 is not equal to 100 the points do not lie on a single line.
