• 2
• 3
• 5
• Cannot be Determined 

How would you write the equation with a slope of 2/3 and a y-intercept of -3

• y=3/2x+3
• y=2/3-3
• y=2/3x-3
• y=2/3x+3

Which equation best represents the line on the graph?

• y= 1/2x
• y= -1/2x
• y = 2x
• y = -2x

What is the equation of the line?

• y = -3/4x + 3
• y = 4/5x + 3
• y = -4/5x + 3
• y = -4/5x

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
