Question

What is the equation for the horizontal line that passes through the point (2,8)?

Answer 1

`y=8`

Explanation:

`"a horizontal line parallel to the x-axis has a special"`
`"equation"`

`color(red)(bar(ul(|color(white)(2/2)color(black)(y=c)color(white)(2/2)|)))`

`"where c is the value of the y-coordinate that the line "`
`"passes through"`

`"here the line goes through "(2,color(red)(8))`

`rArry=8larrcolor(red)"is the equation of horizontal line"`
graph{(y-0.001x-8)=0 [-28.1, 28.08, -14.04, 14.06]}
