Answer 1

An equation is a mathematical sentence with an equal sign = between the two expressions.

A coefficient is the numerical factor that appears before a varible: y=kx.

Equations of the form y=kx represents linear relationships, where k is called the .

Given y=3x. Substitute the value of x to find the value of y.

$\begin{gathered} \text{When x=0, y=3}\ast0=0 \\ \text{When x=1, y=3}\ast1=3 \\ \text{When x=2, y=3}\ast2=6 \\ \end{gathered}$$\frac{y}{x}=\frac{6}{2}=3$
