The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.

Answer:
C
Step-by-step explanation:
A vertical stretch is accomplished by multiplying the parent by the stretch factor (given as 4 in this problem). At that point, the function is
h(x) = 4x
To flip over the x-axis, change the sign of the function's rule.
g(x) = -4x
In the attached image, f(x) = x is purple, h(x) = 4x is black, g(x) = -4x is red.
