Is \( y=5 \) a vertical or horizontal line? Vertical Horizontal

The equation \( y = 5 \) represents a horizontal line. This means that, no matter what the value of \( x \) is, the value of \( y \) will always be 5. Imagine drawing this line on a graph—the line stretches left and right along the y-axis, intersecting it at the point (0, 5). In contrast, a vertical line would be represented by an equation like \( x = a \) (where \( a \) is a constant). These lines go straight up and down, crossing the x-axis at the value of \( a \) while having constant x-values for all y-values. So, if you ever see \( y = c \), you can confidently label it as a horizontal line!
