• Inequality Notation

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

• y = 2x

• y = 1/4 x + 2

• y = 1x + 4

• y = -2x

Find the x and y intercepts
4x - 5y = 40

• x intercept is 10 
  y intercept is 8
• x intercept is 10
  y intercept is 20
• x intercept is 8
  y intercept is 10
• x intercept is 10
  y intercept is -8

What are the x- and y -intercepts on this graph?

• (0,5), (0,5)
• (5,0), (5,0)
• (5,0), (0,5)
• (0,0), (5,0)

Write this equation in standard form y=4x+2

• y=2x+4

• y-2=4x

^{What is the x- intercept of the line?}
