If it is a straight line.
Answer:
y= -2/3x-3
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b. m=Slope. b=y-intercept. Therefore the equation would be y= -2/3x-3
Just compare the change in unit cost to the original unit cost.
Shovels: (70.38 ÷ 2 - (172.50/5) ÷ (172.50/5) = 0.02
Salt: (26.04 ÷ 4 - (6.20) <span>÷ </span>6.20 = 0.05
So, the shovels went up 2% and the salt went up 5%
$.86 (or more specifically .864)
basically just divide 4.32 by 5 :)
