Triangle def is congruent to right triangle ghi with a right angle at vertex h. if the slope of de is –2, what must be true?

the slope of hi is 1/2.

the slope of ef is 1/2.

the slope of gh is –2.

the slope of df is –2.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

c-   36
