Question 1: Using ________, we can determine the limit, or the value that Δy/Δx approaches as Δy and Δx get closer to zero; it follows that this limit is the exact slope of the tangent.  

Question 2: Steamage railway gradient post indicating a slope in both directions at Meols railway station, ________  

Question 3: The ________ of the function at a point is the slope of the line tangent to the curve at the point, and is thus equal to the rate of change of the function at that point.  

Question 4: The concept of slope applies directly to grades or gradients in geography and ________.  

Question 5: In ________, the slope or gradient of a line describes its steepness, incline, or grade.  

Question 6: Through differential calculus, one can calculate the slope of the tangent line to a ________ at a point.  

Question 7: There are two common ways to describe how steep a ________ or railroad is.  

Question 8: Through ________, the grade m of a road is related to its angle of incline θ by  

Question 9: Other curves have "________" slopes and one can use calculus to determine such slopes.
