Spring Review Questions Units 1-5

What does VUX stand for?

• Vertical line, Undefined slope, x= for the equation
• Vertical line, zero slope, x = y for the equation
• Vertical line, undetermined slope, x + 2 = 0
• Victory, Undefined slope, x = y for equation

What does HOY stand for?

• Horizontal line, zero slope, y= # for equation
• Horizontal line, original slope,  y = # for equation
• Horizon, undefined slope, y = # for equation
• Horizontal line, zero slope, y = x for equation

Decide if the given function matches HOY or VUX.

• HOY

• VUX

• NEITHER

Decide if the given function matches HOY or VUX.

• HOY; y = 0

• VUX; x = -3

• HOY; x = -3

• VUX; y = 0

Solve for y.
-10x + 2y = 14

• y = 10x + 12
• y = 10x + 7
• y = 5x + 14
• y = 5x + 7

Solve for y.
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Which value of x makes the equation 2(4x-3) - 8 = 4 + 2x true?

^{Hint use y1, y2, then 2nd, trace, 5 enter five times.}

• x = 5/3

• x = 3

• x = 1

• x = 2

Which value of x makes the equation -8x - 8 +3(x - 2) = -3x + 2 true?

^{Hint use y1, y2, then 2nd, trace, 5 enter five times.}

• x = -8

• x = 8

• x = 2

• x = -2
