Intro to Standard Form of Linear Equations

What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

What is standard form of a line?

• 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

Which of the following are written in standard form?

• y=3x-5
• 3x+16=5y
• 2/3 x + 9/13 y = 21
• 5x+7y=-12

What is the y-intercept of
2x-5y=35?

• (0,-7)
• (-7,0)
• (35/2, 0)
• (0,35/2)

What is the x-intercept of
x+4y=7?

• (7/4, 0)
• (0, 7/4)
• (7, 0)
• (0,7)

Name the x- and y-intercepts for the equation:
5x - 3y = 15

• (3, 0) and (0, -5)
• (0, 3) and (-5, 0)
• (5, 15) and (15, 3)
• (0, -3) and (5, 0)

Write the slope intercept form of the equation x - 3y = 6

• y = -x - 2

• y = x + 2

• y = 1/3x - 2

• y = -1/3x + 2

Put this into standard form:
y = 3x + 2

• y + 3x = 2
• 3x + y = 2
• -3x + y = 2
• 3x - 2y = 2

Find the x and y-intercepts:
y = 5x + 20
**HINT: Cover one variable with your finger and solve for the other

• x-intercept: (0, -4)
  y-intercept: (20, 0)
• x-intercept: (-4, 0)
  y-intercept: (0, 20)
• x-intercept: (5, 20)
  y-intercept: (20, 5)
• x-intercept: (5, 1)
  y-intercept: (20, 5)
