Question

10. The data in the adjacent table depicts the length
of a woman's forehand and her corresponding
height. Based on this data, a student finds a
relationship between the height (y) and the
forehand length() as y = ax + b, where a, b
are constants.
(i) Check if this relation is a function.
(ii) Find o and b.
14) 10th Standard Mathematics

Length 'x' of Height 'y'
Forehand(in cm) (in inches )
35 56
45 65
50 69.5
55 74​

Answer 1

Answer:

(1) this function is a relation as each X has one corresponding value in y

Step-by-step explanation:

x=35, y=56

35a+b=56....(1)

x=45, y=65

45a+b=65 ....(2)

solving equations

we get

a=0.9

b=24.5
