The equation with 15 will be y = 15x.
<h3>What is an equation?</h3>
The equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line. The equation of a line in a general form can be written as below:-
y = mx + c
Where m is the slope and c is the y-intercept. The equation for the constant of proportionality 15 can be written as below:-
y = 15x
Here, y and x are variables and 15 is the constant value and is defined as the slope of the line.
Therefore, the equation with 15 will be y = 15x.
