Q. Is the graph of this equation a horizontal or vertical line?y=−1Choices:(A)horizontal line(B)vertical line
Equation of line: Given equation of line: y=−1Which value remains the same, x or y?y=−1 tells us that the value of y is always −1. It represents that y remains the same.
Type of line: Since y is constant in y=−1, the line is parallel to the x-axis.So, the graph of y=−1 is a horizontal line.
