The line corresponding to y - 4 = 0 it has the following characteristic:
a. it is a horizontal line.
b. it is a vertical line.
c. it is a line with a positive slope.
d. it is a line with a negative slope.

A

Step-by-step explanation:

The equation of a horizontal line, parallel to the x- axis is

y = c

Where c is the value of the y- coordinates the line passes through.

Given

y - 4 = 0 ( add 4 to both sides )

y = 4

This is the equation of a horizontal line

step-by-step explanation:

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
