the last one

Step-by-step explanation:

Perpendicular lines will have one line with a positive slope and one lien with a negative slope first of all.

In the original problem, the slope was 3/4. So the line perpendicular is the reciprocal of 3/4 and it would be negative so -4/3

y = -4/3 x + 1/2

Step-by-step explanation:

y = 3/4 x - 1/2 has a slope of 3/4

The slope of the perpendicular line is the negative reciprocal of the original line's slope, which in this case is -4/3. The line that has this slope is

y = -4/3 x + 1/2

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
