Is the line for the equation y = 1 horizontal or vertical? what is the slope of this line? select the best answer.

the line is horizontal. the slope is 0.
the line is horizontal. the slope is 1.
the line is vertical. the slope is undefined.
the line is vertical. the slope is 0.

slope 0, equation y = 1

Step-by-step explanation:

Think: every point on this line features 1 as the y value.  Thus, the line must be horizontal, and its equation is y = 1.  The slope is 0.  (First answer choice)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
