Exploring Slope Types: Positive, Negative, Zero & Undefined

The video tutorial discusses different types of slopes: positive, negative, zero, and infinite. It explains how to identify each type on a graph and provides real-life examples for better understanding. Positive slopes increase from left to right, while negative slopes decrease. Zero slopes are flat lines, and vertical lines have undefined slopes. The tutorial also includes a step-by-step guide on calculating negative slopes, emphasizing the importance of correctly identifying the slope's sign.

What are the four types of slopes discussed in the video?

• Positive, Negative, Curved, Straight

• Positive, Negative, Horizontal, Vertical

• Positive, Negative, Zero, Infinite

• Positive, Negative, Inclined, Declined

How can you identify a negative slope on a graph?

• It increases from left to right

• It decreases from left to right

• It remains constant

• It forms a horizontal line

What is the slope of a horizontal line?

• Infinite

• Positive

• Zero

• Negative

Why does a horizontal line have a zero slope?

• Because it forms a vertical line

• Because both rise and run are zero

• Because the run is zero

• Because the rise is zero

What is the slope of a vertical line?

• Undefined

• Zero

• Negative

• Positive

Tags

CCSS.8.EE.B.5

Why is the slope of a vertical line considered undefined?

• Because both rise and run are zero

• Because it forms a horizontal line

• Because the rise is zero

• Because the run is zero

What should you remember when calculating the slope of a line with a negative slope?

• The slope should be undefined

• The slope should be zero

• The slope should be a negative number

• The slope should be a positive number
