Since absoulte value makes everything positive asume
y=x+8
y interctpt=8
-y=x+8
multiply -1
y=-x-8
y intercept=-8
= Ratio of minutes to miles in which Samuel drove = 28 : 32
= Ratio of minutes to miles in which Beverly drove = 42 : 48
To find whether the time they drove and the distance they covered were proportional or not , let us first change them into a fraction and then simplify them .
= 28 : 32 = 28/32
= 28/32
Both the numerator and the denominator is divisible by 4 .
= 28 ÷ 4 / 32 ÷ 4
= 7/8 = 7 : 8
Samuel = 7 : 8
Beverly = 42 : 48 = 42/48
= 42/48
Both the numerator and the denominator is divisible by 6 .
= 42 ÷ 6 / 48 ÷ 6
= 7/8
Therefore, the ratio of miles to minutes drove by Samuel and Beverly is proportional , 7:8 :: 7:8
60 people/15 minutes * 60 minute/hr = 240 people/hr
240 people/hr *6 hrs =1440 people
Answer: 1440 people
If you are correcting to a=7 to where 3a = 21 as their are 3 a's which is 7
