Question

What is the 'K' (Constant of Proportionality) for a straight line that goes through the origin with a point of (3, 30).

Answer 1

k = 10

Explanation:

The constant of proportionality of a graph in Mathematics is simply the ratio of y to x which can be called the slope.

It's given by; k = y/x

We are given; y = 30 and x = 3.

Thus;

k = 30/3

k = 10
