Understanding Slope: Concepts and Calculations

The video tutorial explains how to find the slope of a line given two points. It covers the formula for slope as the ratio of vertical change to horizontal change. The tutorial demonstrates calculating the slope for both horizontal and vertical lines, showing that horizontal lines have a slope of zero, while vertical lines have an undefined slope. The video also explains how to use the slope formula and verify results with examples.

What is the slope of a line defined as?

• The ratio of the run to the rise

• The ratio of the vertical change to the horizontal change

• The sum of y-coordinates

• The difference between x-coordinates

How do you find the vertical change when calculating slope?

• By finding the sum of y-coordinates

• By finding the difference in y-coordinates

• By finding the difference in x-coordinates

• By finding the sum of x-coordinates

What is the slope of a horizontal line?

• Zero

• Undefined

• One

• Negative

Which of the following points lie on a horizontal line?

• (2, 3) and (2, 4)

• (0, 0) and (1, 1)

• (-3, -8) and (-3, -9)

• (-5, -2) and (9, -2)

What is the result of dividing zero by any non-zero number?

• One

• Infinity

• Zero

• Undefined

What is the slope of a vertical line?

• Zero

• One

• Undefined

• Negative

Which of the following points lie on a vertical line?

• (-5, -2) and (9, -2)

• (-3, -8) and (-3, -9)

• (0, 0) and (1, 1)

• (2, 3) and (2, 4)

What should you enter when the slope is undefined?

• Negative

• DNE

• Infinity

• Zero

What does 'DNE' stand for in the context of slope?

• Does Not Exist

• Defined Not Equal

• Does Not Equal

• Defined Not Exist

What is the result of dividing a number by zero?

• Undefined

• One

• Infinity

• Zero
