By comparing it with the standard equation : y = mx + c
We get the slope(m) as = - 1/3
Since the product of the slopes of perpendicular lines = - 1,
Slope of the perpendicular line = - 1/(-1/3)
= 3
The perpendicular line passes through the point (1,4) = (x, y)
Using slope point form:
y - y1 = m ( x - x1)
y - 4 = 3 ( x - 1)
y - 4 = 3x - 3
y = 3x + 1 ( option c)

We know that : If Two Lines are Perpendicular to each other, then Product of their Slopes should be Equal to -1
Comparing with Standard form : y = mx + c
We can notice that : Slope of the line is
⇒
⇒ Slope of Line Perpendicular to the given line is 3
We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)
Here the line passes through the point (1 , 4)
⇒ x₀ = 1 and y₀ = 4
We found : Slope(m) = 3
Substituting all the values in the standard form, We get :
Equation of the line : y - 4 = 3(x - 1)
⇒ y - 4 = 3x - 3
⇒ y = 3x + 1
