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

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30
