Finding the Slope Between Two Points on a Graph

Question:
Find the slope of the line passing through each pair of points. Then describe the slope as positive, negative, zero, or undefined. Part a: the points 1 comma 3 and 4 comma 9. Part b: the points negative 2 comma 5 and 3 comma negative 5. Part c: the points negative 4 comma 2 and 6 comma 2. Part d: the points 3 comma negative 1 and 3 comma 7.

Finding the Slope Between Two Points on a Graph

This lesson covers how to calculate the slope of a line passing through two given points using the slope formula. Students practice identifying whether each slope is positive, negative, zero, or undefined by examining four representative examples.

In this lesson, you will learn to:
• Apply the slope formula $m = \frac{y_2 - y_1}{x_2 - x_1}$ to find the slope between two points
• Distinguish between positive, negative, zero, and undefined slopes
• Connect slope values to the visual behavior o
