Understanding Slope and Line Characteristics

This video tutorial teaches how to find the slope of a line from a graph, covering positive, negative, zero, and undefined slopes. It explains the concept of rise over run and demonstrates how to calculate the slope using examples. The video also discusses the properties of horizontal and vertical lines, emphasizing that horizontal lines have a slope of zero, while vertical lines have an undefined slope. The tutorial concludes with a summary of the different types of slopes and encourages further exploration of finding slopes from equations or two points.

What is the formula for calculating the slope of a line?

• Run over rise

• Rise over run

• Difference between rise and run

• Sum of rise and run

If you move 3 units up and 4 units to the right, what is the slope of the line?

• 7/4

• 4/3

• 3/4

• 1/4

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

• The line is vertical

• The line goes up from left to right

• The line is horizontal

• The line goes down from left to right

If you move down 1 unit and 2 units to the right, what is the slope of the line?

• -1/2

• 1/2

• -2/1

• 2/1

Why is the slope the same regardless of which points you choose on a line?

• Because the slope is a property of the line itself

• Because the line is always vertical

• Because the line is always horizontal

• Because the points are always the same distance apart
