Practice: Writing Equations from graphs

Write an equation for the line shown by counting the slope and identifying the y-intercept.

• y = -2x + 2

• y = 2x + 2

• y = 1/2x- 2

• y = -1/2x + 2

What is the equation of this line?

• x=5
• y=5
• y=5x
• x=-5

Write the equation of the line.

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

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

• y = 2x
• y = 1/4 x + 2
• y = 1x + 4
• y = -2x
