Asegment with endpoint a(3.1) and b(-1, -1) is rotated 90° about the origin. what are the
coordinates of a'and b'?
a' (1-3) and b'(-1,1)
a'(-1, 3) and b'(1.-1)
a'(-1, -3) and b'(1.1)
a'(-3,-1) and b(1,1)

i believe the answer is letter c) 8

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
