Adifferent one! the graph of a linear function is shown. which word describes the slope of the line?

a-positive
b-negative
c-zero
d-undefined

C-Zero

Step-by-step explanation:

From the given graph, it can be seen that the line representing a linear function y=-3 is parallel to x-axis.

The slope of x-axis is known to be 0.  

[ ∵ slope= and at x axis the y value remains same (y=-3), so the change in y value is 0 i.e. slope is 0]

Also, the slope of two parallel lines are equal.

Therefore, the slope of the given liner function y=-3 is 0.
