Linear Equations

Which of these represents standard form form?

• y - y1 = m(x-x1)

• Ax + By = C

• y = mx + b

Write the equation in slope-intercept form: 3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Write the equation in slope-intercept form: 2x + y = 41

• x = 2y + 41
• y = 2x -41
• y = -2x + 41
• x = y -39
