Understanding Slope Concepts and Calculations

What does a positive slope indicate about the direction of a line?

• The line is vertical

• The line trends upward

• The line is horizontal

• The line trends downward

Which type of slope is associated with a vertical line?

• Positive slope

• Zero slope

• Undefined slope

• Negative slope

What is the first step in finding the slope from a graph?

• Draw a right triangle

• Pick two ordered pairs on the line

• Calculate the rise over run

• Label the points as x1, y1 and x2, y2

When finding the slope from a graph, what is the 'rise'?

• The hypotenuse of the triangle

• The horizontal change

• The vertical change

• The slope itself

When finding the slope from a table, what is a common mistake?

• Using the same ordered pair twice

• Using the wrong formula

• Using the change in Y over the change in X

• Using the change in X over the change in Y

What should you label your two ordered pairs as when finding the slope from two points?

• x1, y2 and x2, y1

• x1, y1 and x2, y2

• x2, y1 and x1, y2

• x2, y2 and x1, y1

In a table, if the change in Y is 4 and the change in X is 3, what is the slope?

• 3/4

• 4/3

• -4/3

• -3/4

What is the slope of a line that passes through the points (2, 4) and (-5, 8)?

• 4/7

• -7/4

• 7/4

• -4/7

What is the simplified slope of a line passing through (0, 2) and (2, 12)?

• 2

• 6

• 5

• 10

What is another term for the rate of change in real-world situations?

• Slope

• Gradient

• Incline

• Decline
