Q1. Find the slope of the line that goes through the points (-5, -7) and (-5, -9).
Background
Topic: Slope of a Line
This question tests your understanding of how to calculate the slope of a line given two points. The slope describes how steep the line is and whether it rises or falls as you move from left to right.
Key Terms and Formula:
Slope (m): The measure of the steepness of a line.
Formula for slope:
and are the coordinates of the two points.
Step-by-Step Guidance
Identify the coordinates of the two points: and .
Label the points as and .
Plug the values into the slope formula: .
Calculate and separately.
Try solving on your own before revealing the answer!
Final Answer: The slope is undefined.
Since both points have the same x-coordinate (), the denominator of the slope formula becomes zero, which means the slope is undefined. This indicates a vertical line.
