Finding Slope from Two Points Made Easy

This video tutorial by Nancy Foot covers the concept of finding the slope of a line given two points. It introduces the standard formula for slope and provides an alternative, simpler method for calculation. The tutorial includes examples with both positive and negative numbers, demonstrating that the method works consistently. The video concludes with encouragement to practice and an invitation for viewers to ask questions.

What is the formula for finding the slope of a line given two points?

• x2 - x1 over y2 - y1

• x1 - x2 over y1 - y2

• y2 - y1 over x2 - x1

• y1 - y2 over x1 - x2

In the simplified method, what do you do after stacking the coordinates?

• Add the top and bottom numbers

• Subtract the bottom number from the top number

• Multiply the top and bottom numbers

• Divide the top number by the bottom number

What is the slope of the line given the points (1, 2) and (3, 5) using the simplified method?

• 5/3

• 3/2

• 1/2

• 2/3

If you reverse the order of the points, does the simplified method still work?

• Yes, but the slope will be negative

• No, it will give a different slope

• No, it will give an undefined slope

• Yes, the slope remains the same
