Linear Equations From A Graph

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 in slope intercept form.

• y = 2x + 3
• y = 3x + 2
• y = 2x - 1
• y = idk

What is the y-intercept of this graph?

• (0,1)

• (0,3)

What equation matches this graph?

• y = 2x + 2
• y = 3/2x + 2
• y = 1/2x + 2
• y = 2/3x + 2
