- 1.Write down the gradient of the line with equation y = −x + 3.y = −x + 3
- 2.A zip-line runs from a platform 25 m high to a landing point 5 m high, over a horizontal distance of 40 m. Work out the gradient of the zip-line.
- 3.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.
- 4.Work out the gradient of the straight line with equation 3y = 12 − 6x.
- 5.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.
- 6.Work out the gradient of the straight line that passes through the points (−1, 5) and (3, −7).
- 7.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.
- 8.Write down the gradient of the line with equation y = 7x − 2.y = 7x − 2
- 9.A ramp rises 3 m over a horizontal distance of 12 m. Work out the gradient of the ramp.
- 10.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.
- 11.Write down the gradient of the line with equation y = 6 + 4x.
- 12.The graph of a straight line has equation y = 4x − 5. Beth says the y-intercept is 4. Work out the correct y-intercept.y = 4x − 5
- 13.A car's fuel tank contains 50 litres when it starts a journey. After travelling for 2 hours, it contains 38 litres, and fuel is used at a constant rate. Work out the rate at which fuel is used, in litres per hour.
- 14.A straight line has equation y = 4 − 3x. Work out the gradient of the line.
- 15.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.
