Question

Hi. I also need help with this question as well.

Answer 1

B

Explanation:

The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).

The line representing proportional relationship is always straight line passing through the origin and has the equation

`y=kx,`

where k is the coefficient of proportionality.

Substitute coordinates of known point into the equation:

`28=k\cdot 8\\ \\k=(28)/(8)=(7)/(2)=3.5,`

so the coefficient of proportionality is equal to
`3.5.`
