Answer:

y = -2x + 3

Step-by-step explanation:

Let equation of the line be y = mx + b

Since the line is perpendicular to y = 1/2x - 10,

product of the gradient of both lines = -1

therefore,

1/2 x m = -1

m = -2

since it passes through (4, -5),

sub (4, -5):

-5 = -2(4) + b

b = 3

therefore, equation of the line is y = -2x + 3
