Q. Is the graph of this equation a horizontal or vertical line?y=−3Choices:(A)horizontal line(B)vertical line
Equation of line: Equation of line: y=−3Which value remains the same, x or y?y=−3 tells us that the value of y is always −3. It represents that y remains the same.
Value remains same: Equation of line:y=−3Is the line horizontal or vertical?Since y is constant in y=−3, the line is parallel to the x-axis.So, the graph of y=−3 is a horizontal line.
