D. 0

Answer 1

C. Undefined

Explanation:

m= y2-y1/x2-x1

i will use 4 for y2

=4-(-3)/1-1

=7/0

=undefined

Answer 2

Hi there! :)

Answer:

D. 0 and Undefined.

*The answer must have a positive sign.*

Explanation:

`Slope=(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)`

`((-3)-4)/(1-1)=(-7)/(0)=0`

Slope is 0.

Final answer is 0.

Undefined.

Hope this helps!
