Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
You would want to sell the bag of candy in ounces, unless you have way too much candy.
Answer:
40 % increase
Step-by-step explanation:
percent increase = (new - original)/ original
percent increase = (35-25)/25

=.4
multiply by 100
40 percent
A vertical line has no slope so the equation of the line is simply x = constant.
For this question we have:
x = 2
as the equation of the line.
Answer: x = 2
