The equation of the perpendicular line will be y = (4/3)x.

<h3>What is a linear equation?</h3>

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Then the equation of the perpendicular line will be given as

y = - (1 / m)x + c

The equation of line is y = -3/4 x + 1.

Then the equation of the perpendicular line will be

y = 4/3 x + c

The equation is passing through (9, 12), then we have

12 = 4/3 (9) + c

12 = 12 + c

c = 0

Then the equation of the perpendicular line will be y = (4/3)x.

More about the linear equation link is given below.
