Y=2/3x-2 the equation is simply y=mx+b.
M equals the slope while b equals the y-intercept.
What you would have to do is take the 18 and double it because 50% doubled is 100% so when you double 18 it is 36
First off, you'd want to put both fractions with the same denominator, and we simply do so by multiplying each other by the other's denominator.
