Finding Slope from a Graph: Key Concepts and Techniques

This video tutorial covers the concept of slope, including its definition and the four types: positive, negative, zero, and undefined. It explains how to find the slope from a graph using the rise over run method and emphasizes writing the slope as a fraction. The tutorial provides examples of slope calculations and includes practice problems to reinforce learning.

What does the slope of a line represent in a graph?

• The color of the line

• The length of the line

• The steepness or angle of the line

• The curvature of the line

Which type of slope indicates a line going uphill from left to right?

• Negative

• Zero

• Positive

• Undefined

How is slope typically represented in mathematical terms?

• As a fraction

• As a decimal

• As a percentage

• As a whole number

What is necessary to calculate the slope of a line?

• Two specific points on the line

• The length of the line

• At least one point on the line

• The equation of the line

In the context of slope, what does 'rise over run' refer to?

• The horizontal movement over the vertical movement

• The vertical movement over the horizontal movement

• The speed of the rise over the speed of the run

• The length of the line over the width of the line

What is the slope of a line that is perfectly horizontal?

• Negative

• Zero

• Positive

• Undefined

What does a negative slope indicate about the direction of a line?

• It moves vertically

• It moves horizontally

• It moves from bottom left to top right

• It moves from top left to bottom right

How do you determine if a slope is zero?

• The line intersects the y-axis

• The line has multiple points

• The line is horizontal

• The line is vertical

What does an undefined slope typically indicate about a line?

• The line is horizontal

• The line is curved

• The line is vertical

• The line is diagonal

What symbol is used to represent an undefined slope?

• A zero with a slash through it

• A horizontal line

• An infinity symbol

• A vertical line
