Writing and Graphing Linear Equations- Quiz

Write the equation that best matches the graph shown.

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

Write the equation with a slope of -3 and a y-intercept of (0, 4). 

• y = -3x + 4
• y = -12x
• y = x + 4
• 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

Write the equation of the line.

• y= -1x-3
• y= -3x-1
• y=(-1/3)x-1
• y= -3x-3

Write in slope intercept form
-4x + 2y = -6

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

Write -3x + 7y = 14 in slope-intercept form.

HINT: Solve for y

• $y\ =\ \frac{3}{7}x\ +\ 2$

  
  

• $y\ =\ \frac{3}{7}x$

• $y=\ \frac{7}{3}x\ +\ 7$

• y = 3x - 2
