Slope Formula Essentials

What variable is typically used to represent the slope of a line?

• B

• M

• A

• S

Which formula represents the slope of a line?

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

• (y2 + y1) / (x2 + x1)

• (x2 + x1) / (y2 + y1)

If y2 = 7, y1 = 3, x2 = 7, and x1 = 1, what is the slope?

• 3/4

• 4/5

• 2/3

• 1/2

What does a slope of 2/3 indicate in terms of vertical and horizontal changes?

• 2 units down and 3 units left

• 2 units up and 3 units left

• 2 units down and 3 units right

• 2 units up and 3 units right

How many units do we move to the right if the horizontal change is 6 units?

• 3 units

• 4 units

• 5 units

• 6 units

What is the slope if the vertical change is 4 units and the horizontal change is 6 units?

• 1/2

• 3/4

• 2/3

• 4/5

In the geometric approach, what is the slope if you move 3 units to the right and 3 units down?

• 0

• 1

• 3

• -1

Using the slope formula, what is the slope if x1 = -1, y1 = 5, x2 = 2, and y2 = 2?

• -2

• -1

• 0

• 1

What is the result of 2 minus a negative 1?

• 1

• 4

• 2

• 3

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

• It goes up to the right

• It goes up to the left

• It goes down to the left

• It goes down to the right
