Find the Slope and Y-Intercept from Equations

Find the slope(m) and y-intercept (b)

y = -2x

• b = 0

  m = -2

• b = 2

  m = 0

• b = 0

  m = 2

• b = 2

  m = -2

• b = y

  m = x

Write the linear equation given the information:

y-intercept (b) = 8

slope (m) = -6

• y = 8 - 6x

• y = 8 - 6

• y = -6 + 8x

• y = 6 - 8x

Write the linear equation given the information: y-intercept (b) = 10 slope (m) = -2

• y = 10 - 2x

• y = 2 - 10x

• y = -10 + 2x

• y = 10 - 2
  

• a
• b
• c
• d

• a
• b
• c
• d

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

How do you find slope from an equation?

• look at the b value

• look at the number attached to x

• look at the number after the plus or minus sign

• divide the two numbers in the equation
