The equation of the line is [tex]y = kx[/tex] . The special thing about k in this equation is that, it is the slope of the line.
Slope of Line: It is the measure of the steepness. It is calculated as 'rise over run' means change in y divided by x.
Equation of a line using slope-intercept form is:
y = ax + b
where,
Here, in the equation [tex]y = kx[/tex]
k = slope of the line
and y-intercept is zero
Therefore, the special about k in the equation is that k is the slope of the equation [tex]y = kx[/tex].
