Which of the following equation represents a horizontal line that passes through the point (1,-2) 1.x=1 2.y=-2 3.y=-2x+1 4.y=x-2

Respuesta :

Answer:

(2)

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.

The line passes through (1, - 2) with y- coordinate - 2, thus

y = - 2 ← is the equation of the line
