bear in mind that, direct proportional equations have a y-intercept.
for y = kx, is pretty much y = kx + 0, where 0 = y-intercept.
and the "k" constant of proportionality, is pretty much just its slope.
Answer:
9 gallons were used
Step-by-step explanation:
There are 8 pints to 1 gallon
72 jars holding 1 pint each means 72 pints total
72/8=9
Beth used 9 gallons
