Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located?

1 thought on “Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located?”

1. The value of A is A(1,-15) and the distance between AB is 8 so these are the correct answers.

   According to the statement

   We have given that the

   AB = 8 and B lies at −7, and we have to find the position of the A on the number line.

   Let a be a point on number line and b be the second point on number line.

   And The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.

   Here

   AB = 8

   B = -7

   We have to look at the options one by one.

   For A = -1

   As A>B

   AB = -1-(7) = -1+7 = 6

   For A = 1

   As A>B so

   AB = 1-(-7) = 8

   So with A = 1 , AB = 8

   This is one of the right answers.

   For A=15

   As A>B

   AB = 15-(-7) = 22

   For A=-15

   As B>A

   AB = -7 -(-15) = 8

   As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.

   So, The value of A is A(1,-15) and the distance between AB is 8 so these are the correct answers.
