Exploring Slope and Rate of Change in Graphing Lines

What is the definition of slope?

• Change in x divided by change in y

• Sum of x and y coordinates

• Difference between x and y coordinates

• Change in y divided by change in x

What are the coordinates of the two points used to calculate the slope of Line A?

• (3, 6) and (1, -6)

• (3, -6) and (-1, 6)

• (3, 6) and (-1, -6)

• (3, -6) and (1, 6)

What is the slope of Line A?

• 3

• 12

• 4

• 1

What is the slope of Line B?

• 1/2

• 3

• 1

• 2

How do you ensure the correct order of operations when calculating slope?

• Subtract the x-coordinates first, then the y-coordinates

• Use the same order for both x and y coordinates

• Always subtract the smaller coordinate from the larger one

• Subtract the y-coordinates first, then the x-coordinates

What is the slope of Line C?

• -2

• 2

• -1

• 1

What does a negative slope indicate?

• As x increases, y decreases

• The line is horizontal

• The line is vertical

• As x increases, y increases

What is the slope of Line D?

• 1/2

What is the slope of a vertical line?

• Infinity

• Undefined
