Answer:

The answer to your question is the letter C.

Explanation:

Data

original line y = 4/3x + 1

Point = (4, 1)

perpendicular line = ?

Process

1.- Find the slope of the original line. The slope is the coefficient of the x.

y = 4/3x + 1

slope = 4/3

2.- Find the slope of the perpendicular line

slope = -3/4

3.- Find the equation of the new line

y - y1 = m(x - x1)

y - 1 = -3/4(x - 4)

y - 1 = -3/4x + 3/4(4)

y = -3/4xx + 3 + 1

y = -3/4x + 4

4.- Find the y-intercept

The y-intercept is the number after the x.

y = -3/4x + 4

y-coordinate = 4
