  • The gradient of a graph represents a rate of change
  • The gradient tells us how much the line goes up for every one unit it goes along the x axis
  • The physical meaning of the gradient can be determined by looking at the labels on the axes
  • A steeper gradient represents a greater rate of change
  • The initial value can be found using the y intercept
  • The gradient can be calculated by finding any two coordinates on the line and using the formula
  • The gradient represents the rate of change in the given quantity
  • The rate of increase can be determined by the value of the gradient
