The slope represents ...

• the difference of the y-values over the difference of the x-values

• the rate of change

• how much something costs

• the second point
• a slope of 2
• the first point

Using the points from the beginning of the video, (10, 20) and (15, 30), we can say that y₂ = ​ (a)   , y₁ = ​ (b)   , x₂ = ​ (c)   , and x₁ = ​ (d)   .
