Analysis of Linear Functions

Trick Question?#6 x = ?

This is a VERTICAL line.Slope (m) – UNDEFINED

Steepness – MORE or NO SolutionY intercept (b) / (0,b) NO SOLUTION

Increasing/Decreasing really Neither

What is the parent linear function?

y = x

What is the parent linear function?

y = x

What is the parent linear function?

y = x

What is the parent linear function?

y = x

What is the parent linear function?

y = x

What is the parent linear function?

y = x

What is the slope? m =

y = 6x + 4y = -¾x + 1y = 8y = -5x – 2y = ⅞x - 9

What is the slope? m =

y = 6x + 4y = -¾x + 1y = 0x + 8y = -5x – 2y = ⅞x - 9

MORE steep or LESS steep

y = 6x + 4y = -¾x + 1y = 8y = -5x – 2y = ⅞x - 9

MORE steep or LESS steep

y = 6x + 4 6>1y = -¾x + 1 ¾<1y = 0x + 8 0<1y = -5x – 2 5>1y = ⅞x – 9 ⅞<1

MORE steep or LESS steep

y = 6x + 4 6>1 MOREy = -¾x + 1 ¾<1 LESSy = 0x + 8 0<1 LESSy = -5x – 2 5>1 MOREy = ⅞x – 9 ⅞<1 LESS

What is the y intercept? b = Coordinates

y = 6x + 4y = -¾x + 1y = 8y = -5x – 2y = ⅞x - 9

What is the y intercept? b = Coordinates

y = 6x + 4y = -¾x + 1y = 0x + 8y = -5x - 2y = ⅞x - 9

What is the y intercept? b = Coordinates

y = 6x + 4 (0 , 4)y = -¾x + 1 (0 , 1)y = 0x + 8 (0 , 8)y = -5x - 2 (0 , -2)y = ⅞x - 9 (0 , -9)

Increasing or Decreasing

y = 6x + 4y = -¾x + 1y = 8y = -5x – 2y = ⅞x – 9

Increasing or Decreasing

y = 6x + 4 positive slope

y = -¾x + 1y = 8y = -5x – 2y = ⅞x – 9 positive slope

Increasing or Decreasing

y = 6x + 4 positive slope

y = -¾x + 1 negative slope

y = 8y = -5x – 2 negative slope

y = ⅞x – 9 positive slope

Increasing or Decreasing

y = 6x + 4 positive slope

y = -¾x + 1 negative slope

y = 8 horizontal line NEITHER

y = -5x – 2 positive slope

y = ⅞x – 9 positive slope
