Tobin Test 1

Find the equation of the line that passes through the points:
(-4, -2) and (-3, 5)

• y = ¹/₇ x + 26
• y = 7x + 26
• y = -7x + 26
• y = -7x - 26

Write the equation of the line in slope-intercept form with slope m = 4 through the point (-2, 5).

• y = 4x - 13

• y = 4x + 13

• y = 4x - 3

• y = 4x + 3

Write the slope intercept form of the equation

3x - 2y = -16

Is this relation a Function?

• Yes
• No
• I Don't Know

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.

The graph of a function is shown.  What are the domain and range of this function?

• Domain: (-∞, ∞)
  Range: (-∞, 2]
• Domain: [2, ∞)
  Range: (-∞, ∞)
• Domain: (-∞, ∞)
  Range: (-∞, ∞)
• Domain: (-∞, 2]
  Range: [2, ∞)

What is the range?

• x = 2

• −∞ < x < ∞

• y = 2

• none of these

What is the Domain?

• $\left(-\infty\ ,\ 4\ \right)$

• ( -2 , 2 )

• [ -3 , 2 )

• [ -5 , 4 ]
