Answer:
4x - y - 12 = 0
Step-by-step explanation:
To find the equation of a line when a point passing through it and its slope are give we use slope and one - point form
It is given by: [tex]y - y_1 = m(x - x_1)[/tex].
where, [tex](x_1, y_1)[/tex] is the point that passes through it and m is the slope of the line.
Substituting we have: [tex]y - 0 = 4(x - 3)[/tex]
[tex]\implies y =4x - 12[/tex]
[tex]\implies 4x - y - 12 = 0[/tex].
