Lesson 12-3: Standard Form (10/30)

What does "m" represent in y=mx+b?

• y-intercept

• slope

• Minecraft

• nothing

What is the Standard Form of a linear equation?

• y = mx + b

• Ax + By = C

What is the formula for Slope-Intercept Form?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

What is the y intercept?

y = 2x - 3

• 3

• -3

• 1

• 2

Find the slope and y-intercept of the following:

y = -8x + 13

• slope = -8/13, y-intercept = 1
• slope = -8, y-intercept = 13
• slope = 8/13, y -intercept = -8
• slope = 13, y-intercept = -8

What is the slope:

5x + 10y = 30

• m = -1/2

• m = 1/2

• m = 1/3

Give the y-intercept

3x + y = 5

• (-3, 0)

• (0, 5)

• (-5, 0)

Give the x-intercept

3x + 8y = 24

• (8, 0)

• (0, -8)

• (0, 3)

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 10

  y intercept is -8
