From the problem, the slope is -3 and the y-intercept is 0
Note that in any equation in the slope-intercept form,
[tex]y=mx+b[/tex]
m is the slope
and
b is the y-intercept
From the given,
m = -3 and b = 0
Subsitute it to the formula :
[tex]\begin{gathered} y=-3x+0 \\ y=-3x \end{gathered}[/tex]
The equation of the line is y = -3x
