Write the equation in slope intercept form.

• y = 2x + 3

• y = 3x + 2

• y = 2x - 1

Write the equation of the line.

• y = -1/3x - 2

• y = 1/3x - 2

• y = 3x - 2

• y = -3x - 2

What is the equation of the line?

• y = -3/4x + 3

• y = 4/5x + 3

• y = -4/5x + 3

• y = -4/5x

What is the slope?

• -1/3

• -3

• -4

• 5

Jenny writes the equation y = 1/2x +5.
Why is she incorrect?

• The slope is -2, the equation should be
  y = -2x + 5

• The y-intercept is 4, the equation should be y = -2x + 4

• The slope is -1/2, the equation should be
   y = -1/2x + 5

• The y-intercept is -5, the equation should be y = -2x - 5
