Answer:
Non Proportional
Step-by-step explanation:
nonproportional
If a gallon costs 1.99 then a half gallon should be at least a little cheaper because it is only half of a gallon.
y-2 = -(x-2)
To find the slope
m = (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are two points on the line
= (1-3)/(4-2)
=-2/2
=-1
The point slope form is
y-y1 = m(x-x1) wher m is the slope and (x1,y1) is a point on the line
y-3 = -1(x-2)
271,403 is rounded to 270,000 because the 1403 before it is less than 5000, 4 and below drop it down, 5 or more bump it up.
