The number of young adult hikers in a country has steadily increased since 2010 the equation y=0.89x+9.78 can be used to estimate the number of young adults participating in hiking in the country ,in millions ,x years after 2010 a.) estimate the number of young adult hikers in the country in 2017 ? B.) in what year will 18.8 million young adults participate in hiking in the country ?

0 is its x and y coordinate

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
