What is the most important consideration when selecting points on a graph to determine slope?

The points must have exact x and y coordinates.

Explain why points without exact x and y coordinates cannot be used to accurately calculate the slope from a graph.

Without exact coordinates, it's impossible to determine the precise rise and run, leading to an inaccurate slope calculation.

The slope is constant throughout a straight line; it remains the same no matter which two points are selected.

How to Find the Slope on a Graph: With No Points!

Algebra-1 with Mr. Peters

8 min

Key concepts students will learn:

•
When finding slope from a graph, it is important to choose points that line up on an exact x and an exact y.
•
The slope of a linear equation is the same throughout the entire line, so it doesn't matter which points you pick as long as they line up on an exact x and y.
•
To find the slope, count the rise over the run and keep it as a fraction.
