Answer:
The statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2 ⇒ C
Step-by-step explanation:
Let us revise the facts of the horizontal line:
- The line is horizontal if all points on it have the same y-coordinates
- The horizontal line is parallel to the x-axis
- The slope of the horizontal line is zero
- The equation of the horizontal line is y = b, where b is the y-coordinate of all points on the line
- The y-intercept of the horizontal line is (0, b)
∵ The equation of the line is y = -3
→ Which means the value of y = -3 at any value of x
∴ The line is horizontal
∴ Its slope = 0
∵ The horizontal line is parallel to the x-axis
∴ The line does not intersect the x-axis
∴ The true statements are:
- It is the equation of a horizontal line
- The line does not cross the x-axis
The statement which is NOT true about the equation y = -3 is
It is perpendicular to the equation y = 1/3x + 2
