- 1.Line C passes through (0, 0) and (4, 2). Line D passes through (0, 0) and (2, 2). Write down which of the two lines is the steeper.
- 2.A hot air balloon is at a height of 20 m and rises at a steady rate. After 4 minutes it is at a height of 52 m. Work out the rate at which the balloon rises, in metres per minute.
- 3.Work out the gradient of the straight line with equation 3y = 12 − 6x.
- 4.Work out the coordinates of the point where the graph of y = 2x − 6 crosses the x-axis.y = 2x − 6
- 5.A tank already contains some water and is then filled at a constant rate. After 2 minutes it contains 50 litres in total; after 7 minutes it contains 150 litres in total. Work out the rate at which water is added, in litres per minute.
- 6.Write down the gradient of the line with equation y = −x + 3.y = −x + 3
- 7.A mobile phone plan charges a fixed monthly fee plus an amount for each gigabyte of data used. The total cost £C for using g gigabytes in a month is given by C = 15 + 2g. What does the number 2 represent in this formula?
- 8.A car passes the 15 km marker on a road and passes the 195 km marker 3 hours later. Work out the gradient of the distance-time graph, that is the rate of change of distance with time.
- 9.Work out the gradient of the straight line that passes through the points (−1, 5) and (3, −7).
- 10.Work out the gradient of the straight line with equation 2x + y = 8.
- 11.A straight line has equation y = 4 − 3x. Work out the gradient of the line.
- 12.The graph of y = mx + 6 passes through the point (−2, 0). Work out the value of m.
- 13.Work out the gradient of the straight line with equation y = (2x/5) − 3.
- 14.A printer starts a job with 480 sheets of paper loaded and prints at a steady rate. The number of sheets left, S, after t minutes is given by S = 480 − 24t. Work out how many minutes it takes for the paper to run out completely.
- 15.A straight line has equation 4y = 12x + 20. Work out the gradient of the line.y = 12x + 20
