Q. Is the graph of this equation a horizontal or vertical line?y=−8Choices:(A) horizontal line(B) vertical line
Equation of line: Equation of line: y=−8Which value remains the same, x or y?y=−8 tells us that the value of y is always −8. It represents that y remains the same.
Value remains same: Equation of line:y=−8Is the line horizontal or vertical?Since y is constant in y=−8, the line is parallel to the x-axis.So, the graph of y=−8 is a horizontal line.
