Question

Determin The Constant of proportionality
l varies derectly as h; when l = 112,h = -16

Answer 1

-7

Explanation:

l = kh . . . . . l is proportional to h with proportionality constant k

112 = k·(-16) . . . . . . use the given numbers

k = -112/16 = -7 . . . divide by the coefficient of k

The constant of proportionality is -7.
