Calculating the Slope from Two Points

What is the primary method to find the slope of a line when given two points?

• Using a graph

• Calculating the area under the curve

• Applying the slope formula

• Estimating visually

What does the numerator in the slope formula represent?

• Horizontal change

• Vertical change

• Midpoint of the line

• Length of the line

What does the denominator in the slope formula indicate?

• Slope intercept

• Distance between points

• Horizontal change

• Vertical change

How do you calculate the slope if you are given the points (x1, y1) and (x2, y2)?

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

• None of the above

• (y2 + y1) / (x2 + x1)

If point one is (3, -4) and point two is (-3, 5), what is the slope of the line?

• -2/3

• 2/3

• -3/2

• 3/2

What is the result of the slope calculation for points (-3, 5) and (3, -4)?

• 3/2

• 9/6

• -3/2

• -9/6

What happens to the slope calculation if the order of the points is reversed?

• The formula no longer applies

• The slope remains consistent

• The slope value changes

• The slope becomes positive

If the points are switched and recalculated, what should be the outcome for the slope?

• The slope becomes zero

• The slope inverts its sign

• The calculation becomes invalid

• The slope value remains the same

Which of the following is equivalent to -3/2?

• -2/3

• 2/3

• 3/-2

• 3/2

Which statement is true regarding the slope formula?

• It changes with the order of points

• It only works with positive numbers

• It can be used without seeing the line

• It requires a graph to be effective
