How to find the slope between two points

The video tutorial explains how to find the slope between two points. It begins by defining slope as 'rise over run' and introduces the concept of change in elevation and horizontal distance. The tutorial then explains the use of delta notation to represent changes in coordinates. It guides viewers on labeling points with subscripts to differentiate them and demonstrates the calculation of slope using an example. Finally, it discusses interpreting slope values and converting them into fractional form for graphing purposes.

What is the common phrase used to describe the concept of slope?

• Rise over run

• Distance over time

• Height over base

• Run over rise

How is the change in slope mathematically represented?

• X1Y1 over X2Y2

• Y1X1 over Y2X2

• Delta Y over Delta X

• Delta X over Delta Y

Why do we use subscripts when labeling points?

• To make the points look different

• To differentiate between the two points

• To avoid using numbers

• To make calculations easier

What is the result of subtracting Y1 from Y2 in the example calculation?

• 4

• 12

• -4

• -12

How can a whole number slope be expressed in fractional form?

• By adding zero

• By multiplying by two

• By dividing by one

• By subtracting one
