A horizontal line, parallel to the x-axis is a line that passes through all points in the plane with the same y- coordinate. For this reason it's equation in general is #color(blue)" y = c"# , where c is the value of the y-coordinate that it passes through.

Here the y- coordinate is - 5

#rArry=-5" is the equation of the line"#

graph{y-0.001x+5=0 [-25.66, 25.66, -12.83, 12.83]}
