• y-intercept

• banana

• nothing

• slope

What is the slope in the equation y=2x + 3?

• 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

Which equation represents the following graph?

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

Write the equation for the line in slope-intercept form.

• y= -1x+3
• y= 4x+3
• y=1/4x+3
• y= -4x+3

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

Find the slope

• -5/7
• 7/5
• -7/5
• 5/7

What is an equation for the line that passes through the coordinates (2,7) and (0, 1)?

• y = 3x + 1
• y = 1x + 3
• y = x - 3
• y = -x + 3
