Exploring the Concept of Slope

The video tutorial explains the concept of slope as the ratio of rise to run, emphasizing that it is calculated by moving vertically before horizontally. It demonstrates how to find slope using graphs by selecting points that cross whole numbers and calculating the rise over run. The tutorial also covers finding slope using ordered pairs, explaining the formula and the importance of consistency in calculations. Various examples illustrate different scenarios, including undefined and zero slopes.

What is the ratio used to define slope?

• Run over rise

• Rise over run

• Up and down over side to side

• Side to side over up and down

When plotting points, which direction do you go first?

• Up and down

• Side to side

• Diagonal

• It doesn't matter

How do you find the slope from a graph?

• By counting the rise and run between two points

• By drawing a line through the origin

• By measuring the angles

• By using a protractor

What is the simplified form of the slope if the rise is 2 and the run is 1?

• 1/2

• 2

• 2/1

• 1

What is the slope if you go down 6 units and to the right 4 units?

• -3/2

• 3/2

• -2/3

• 2/3

What is the slope of a line that goes up 1 unit and over 0 units?

• 0

• 1

• Undefined

• Infinity

What is the slope of a line that rises 0 units and runs 2 units?

• 0

• 2

• Undefined

• 1

What is the formula for calculating slope from two points?

• (Y2 + Y1) / (X2 + X1)

• (X2 - X1) / (Y2 - Y1)

• (Y2 - Y1) / (X2 - X1)

• (X2 + X1) / (Y2 + Y1)

If you have points (4, 1) and (1, 3), what is the slope?

• -2

• 2

• -1/2

• 1/2

What is the slope if you have points (6, 2) and (4, 2)?

• 1

• 0

• Undefined

• 2
