2-2 Linear Equations B

To identify non-linear equations, we look for...

• exponents

• parentheses

Select the linear equation.

• 
• 

Why is this function linear?

• This is a linear function because it does not have a constant rate of change

• This is a linear function because it creates a curved line.

• This is a linear function because it have a constant rate of change.

• This is a linear function because it's y-intercept is (0,2)

Which equation is linear?

Given the list of ordered pairs, identify the y-intercept.(1, 3),  (9,10),  (0, -4),  (8, 9),  (4, 0)

• (1,3)

• (0,-4) and (4,0)

• (0,-4)

• 3, 10, -4, 9, 0

Give the x-intercept of the graph for

3x + 8y = 24

• (8, 0)

• (0, 8)

• (3, 0)

• (0, 3)

What is the y-intercept for the given graph?

• -5

• 5

• 1

• -1

What is the x and y intercept for the following equation ?

4x - 10y = 20

• x - int = 4    

  y-int = -10

• x-int = 5

  y-int = 2

• x - int = 5

  y int = -2

• x -int = 4

  y -int = -10

Write in standard form.

y = -3x + 5

• y = -3x + 5

• 3x + y = 5

• 3x - y = 5

• -3x + y = -5

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y-y₁ = m(x-x₁)

• y = Ax + By
