Randall says he can use the information in the figure to prove BCD is congruent DAB

yes he can

Step-by-step explanation:

Using ASA congruency theorem:

angle ABD=CBD=ADB=CDB and BD concludes they are congruent triangles

hi there!

the answer will be d: 2

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
