1. Write an algebraic equation to represent Car A. 2. Write an algebraic equation to represent Car B.
3. Which car is faster?

1. y= 3x+1, 2. y= x+6, 3. car A

Step-by-step explanation:

the equation is the rule that is followed to find y (the distance the car traveled)

Car A

find a rule to get from x= 2 to y= 7 that also works to get from x= 3 to y =10 and so on... and will find that 3x +1 works for all.

the rule ( the equation) is y= 3x + 1 ; (because 7= 3*2 +1, 10 = 3*3 +1,...)

Car B

y= x+6; (because 6= 0+6, 11= 5+6, ...)

faster means speed so a higher miles per hour rate so that will be represented by the slope of the line the equation gives

y=mx +b is the equation of a line where m -is the slope

y=3x+1 has the slope 3 (car A)

y= x+6 has the slope 1 (car B)

3 > 1 so car A is faster

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
