1.3 Lesson 2 Rearranging Equations of Lines

Multiple Choice

Which of the following is the best first step to isolate x in the equation

14 = 3x - 28c?

• Add 28c to both sides

• Divide both sides by 3

• Subtract 14 from both sides

• Multiply both sides by 3

Multiple Choice

Which of the following is the correct solution for x in the equation

14 = 3x - 28c?

• (14 + 28c)/3

• (14 - 28c)/3

• (14 + 3c)/28

• (14 - 3c)/28

Multiple Choice

What is the slope and y-intercept of the equation 5x + 6y = 30?

• Slope: -5/6,

  y-intercept: 5

• Slope: 5/6,

  y-intercept: 6

• Slope: -6/5,

  y-intercept: 30

• Slope: 6/5,

  y-intercept: 0

Multiple Select

Rewrite the equation y = (2/5)x - 4 in standard form.

• -2/5x + y = -4

• 2x - 5y = 20

• x - y = 4

• All of the above

Multiple Choice

What is the form of the linear equation given in 6x - 9y = -12?

• Standard form

• Slope-intercept form

• Point-slope form

• Quadratic form

Multiple Select

Which of the following sets contains equations that are all equivalent to each other?

• Set 1:

  -6x + 4y = 24,

  y = (3/2)x + 6,

  (y - 6) = (3/2)x

• Set 2:

  -4x - 6y = 24,

  y = -(2/3)x - 4,

  (y - 6) = -(2/3)(x + 15)

• Set 3:

  4x - 6y = 24,

  f(x) = (2/3)x - 4,

  (y + 6) = (2/3)(x + 3)

• All of the above
