Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we
Serjik [45]
The first thing we are going to do for this case is define variables.
 We have then:
 x: number of gallons of water
 y: total weight
 We then have an equation of the form:
 y-yo = m (x - xo)

 Where,
 m = (y2 - y1) / (x2 - x1)

 Substituting values:
 m = (196.8 - 113.4) / (20 - 10)

m = 8.34
 We choose an ordered pair:
 (xo, yo) = (10, 113.4)

 Substituting values:
 y-113.4 = 8.34 (x - 10)

 Rewriting:
 y = 8.34x - 83.4 + 113.4

y = 8.34x + 30
 Answer:
 
y = 8.34x + 30
