For the line connecting the points ( 1, 7 ) and ( 3, -1 ), find the linear equation.

Type your answer in the form y=mx+c and type your equation without any spaces between letters, numbers and symbols.

You can work this out by either graphing the coordinates and determining the gradient and y-intercept from the graph or by solving via substituting a coordinate into the equation.

The tap on a tank has been left on and water is running out. The volume of water in the tank after 1 hour is 100L and after 5 hours the volume is 20L. Assuming the relationship is linear, find the gradient of this relationship.

(It may help to graph the above information first and think of the values as coordinates on a cartesian plane).
