Lines c and d are perpendicular. if the slope of line c is -4, what is the slope of line d?

a. -1/4
b. 1/4
c. -4
d. 4

The slope of line d is A. -1/4

Step-by-step explanation:

To find the slope of a line perpendicular to another one, you take the first line's slope's reciprocal and multiply it by -1.

4's reciprocal is 1/4

1/4*-1 = -1/4

the answer is b i just did that

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
