Question

Label the if the slopes of these lines are positive, negative, zero, or undefined slope

A
B
C
D​

Answer 1

Explanation:

A positive : from left to right it goes up.

B negative : from left to right it goes down.

C negative : from left to right or goes down.

D positive : from left to right it goes up.

a zero slope would be a horizontal line (not going up, not going down, just a flat line).

an undefined slope would be a vertical line. x cannot change at all, but y takes every value from -infinity to +infinity at the same time.
