• What is the general equation of a straight line?

  Not always in the form y = mX + C
• How do you find the gradient, y-intercept, and x-intercept of the equation 3x + 2y = 4?

  • Rearranging to slope-intercept form:

  1. 2y = -3x + 4
  2. y = -3/2x + 2

  • Gradient: -3/2
  • y-intercept: (0, 2)
  • x-intercept: (4/3, 0)
