Slope Basics

1. What is the slope formula?

• run/rise
• y₂-y₁/x₁-x₂
• y₂-y₁/x₂-x₁
• x₂-x₁/y₂-y₁

Find the slope of the line that passes through each pair of points. 
3. (6, 3), (7, -4)

• -7
• 1/7
• -1/7
• 7

Find the slope of the line that passes through each pair of points. 
4. (-9, -3) (-7, -5)

• 1/2
• -2/-2
• -1
• 2/1 

Find the slope of the line that passes through each pair of points. 
5. (3, 9) (-2, 8)

• 1
• 1/1
• 5
• 1/5

6. (0.2, -0.9) (0.5, -0.9)

• 0
• undefined
• -1.8/-0.3
• 1.8/0.3

Find the slope of the line that passes through each pair of points. 
7. (2, 5) (-3, -5)

• 0
• 1/2
