Write an equation for the relationship shown on this graph if the price per ticket is doubled.

y = 2x

linear equations are just finding the right ratio and putting it in y = mx+b format

this graph is saying that two dollars are earned for every ticket sold, a 2:1 ratio.

so the equation would be y = 2x, two being the amount of money collected for one ticket, and x being the number of tickets sold.

homozygous. one is homozygous, while two is heterozygous.
