Slope from Two Points

The video tutorial explains how to find the slope of a line using two points. It begins with an introduction to the concept of slope, describing it as the steepness of a line and a ratio of the change in Y over the change in X. The tutorial then introduces the slope formula, explaining how to use it with examples. It covers different types of slopes, including positive, negative, zero, and undefined slopes, and demonstrates how to calculate them using given points. The video also discusses the graphical representation of slopes and how to use graphs to find slope.

What is the slope of a line in terms of Y and X?

• The product of Y and X

• The ratio of the change in Y to the change in X

• The difference between Y and X

• The sum of Y and X

Which variable is commonly used to represent slope in algebra?

• N

• M

• S

• L

When using the slope formula, what must you ensure about the points?

• They must be on the same line

• They must be in alphabetical order

• They must be in numerical order

• They must be in different quadrants

What is a common mistake students make when calculating slope?

• Using addition instead of subtraction

• Forgetting to use parentheses

• Switching the X and Y differences

• Using multiplication instead of division

What is the slope of a horizontal line?

• Undefined

• Positive

• Negative

• Zero

What type of slope does a vertical line have?

• Zero

• Positive

• Negative

• Undefined

If a line has a slope of -3/2, what can be said about its direction?

• It is horizontal

• It is vertical

• It slopes upwards

• It slopes downwards
