What is the correct equation in 
Slope-Intercept Form?
(y = mx +b)

• y = 1/3x - 1
• y = 1/4x -1
• y = -1/3x +1
• y = -1/4x + 1 

Find the slope between the two points.
(3, 7) and (-4, 2)

• ⁷/₅
• ⁵/₇
• ²/₃
• 2

5(x-4) = 3(2x-5)

• No Solution
• One Solution
• Infinitely Many Solutions

• No Solution

• Infinite Solutions

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

_{What is the y-intercept of the line?}

• y = 1/2
• y = 1
• y = -1/2
• y = -1

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)
