Finding Equation of a Line from a Graph

 Identify the slope-intercept equation:

• y = 2x - 2
• y = -2x + 2
• y = -2x + 4
• y = 2x + 4

Find the slope of the line.

• -5/4
• 5/4
• -4/5
• 4/5

The equation of the following line is 

• x = 5
• x = 3
• x = 4
• x =7

Which equation matches the graph? (Click me to see the image)

• y = -1/4x + 2

• y = 1/4x + 2

• y = 1x + 4

• y = 4x + 2

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

• y=-1x+3
• y=4x+3
• y=¼x+3
• y=-4x+3

Which equation is being represented by this line?
