Is the function Linear or Nonlinear?

• Linear

• Nonlinear

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

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write the equation of the line.

• y= -1x-3

• y= -3x-1

• y=-1/3x-1

• y= -3x-3

Write in slope intercept form. 2x + y = 2

• y = -2x

• y= 2x + 2

• y= -2x + 2

• x = -2x + 2

Put the equation in slope-intercept form: 
2x + 2y = 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6
