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.
