Maths KS4 - Lesson 3: Straight line graphs
Screen 2a: Straight line graphs have the form y = mx + c. m is the gradient: the rate of change. It is a measure of how much y changes with each value of x. c is the intercept: the value of y when x = 0.
Screen 2b: Straight line graphs have the form y = mx + c. m is the gradient: the rate of change. It is a measure of how much y changes with each value of x. c is the intercept: the value of y when x = 0.
Screen 3: Barges must dock at each Tideway foreshore site. Because the River Thames is tidal in some parts, the barges must not sink too low as they are loaded with spoil.
Screen 4: Different barges take different times to load. This depends on how fast the barge can tie or untie from the dock, and how long it takes to load each tonne of spoil into the barge. These times vary depending on the barge design.
