Question

Can you help me with this task to understand it

Answer 1

Answer:

1) Constant of proportionality, k = 2

Explanations:

The given relationship for the graph is y = kx

Where k is the constant of proportionality

The constant of proportionality, in this case, can also be regarded as the rate of change of y with x

We are going to pick the coordinates of any two points on the line and find the slope (constant of proportionality)

Let us pick the points (1, 2) and (2, 4)

`k\text{ = }(4-2)/(2-1)`

k = 2 / 1

k = 2
