The equation of the perpendicular line is y = 3x/4 + 10/3

How to determine the equation of the perpendicular line

From the question, we have the following parameters that can be used in our computation:

4x + 3y = 10

In slope intercept form, we have

y = -4x/3 + 10/3

The slope of the above line is -4/3.

Perpendicular lines have slopes that are negative reciprocals of each other.

So, the perpendicular slope is 3/4.

The given line has a y-intercept of 10/3.

Since the perpendicular line has the same y-intercept as the given line, its y-intercept is also 10/3.

So, the line equation is

y = 3/4x + 10/3

Hence, the equation of the perpendicular line is y = 3x/4 + 10/3.
