The elements that are visible include A, B, and C.
The equation of the perpendicular line can be identified by determining its slope and applying the given point within the standard formula.
Standard equation: y-y1 = m(x-x1)
m*m'=-1
where m' indicates the slope of the perpendicular line
m denotes the slope of the original line
m = -coefficient of x/coefficient of y = -4/-3 = 4/3
m' = -3/4
Substituting the point (3, -2):
y+2 = -3/4*(x-3)
4y+8 = -3x+9
Thus, the equation of the perpendicular line is: 3x+4y-1=0
We apply the slope formula by substituting the given points.

Here, x2 equals 5 and x1 equals -2; y2 equals -3 and y1 equals 6.

Thus, the line's slope is -9 divided by 7.
