Graphs
Akopọ
Graphs give you a way to see algebra. Every equation you write down corresponds to a curve or a line on a set of axes, and reading that picture tells you things the algebra alone can hide: where a quantity reaches its maximum, how fast something is changing, or where two conditions are satisfied at once.
This topic starts with the coordinate system itself and builds up through straight-line graphs to quadratics and, at Higher tier, cubics, reciprocals, and trigonometric curves. You will learn to find gradients, write equations of lines, and apply transformations to function graphs.

- Interpret information presented in a range of linear and non-linear graphs
- Understand and use conventions for rectangular Cartesian coordinates
- Plot points (x, y) in any of the four quadrants or locate points with given coordinates
- Determine the coordinates of points identified by geometrical information
- Determine the coordinates of the midpoint of a line segment, given the coordinates of the two end points
- Draw and interpret straight line conversion graphs
- Find the gradient of a straight line
- Recognise that equations of the form y = mx + c are straight line graphs with gradient m and intercept on the y-axis at the point (0, c)
- Recognise, generate points and plot graphs of linear and quadratic functions
- [Higher] Recognise, plot and draw graphs with equation y = Ax^3 + Bx^2 + Cx + D and related reciprocal and trigonometric forms
- [Higher] Apply to the graph of y = f(x) the transformations y = f(x) + a, y = f(ax), y = f(x + a), y = af(x) for linear, quadratic, sine and cosine functions
- [Higher] Interpret and analyse transformations of functions and write the functions algebraically
- [Higher] Find the gradients of non-linear graphs by drawing a tangent
- [Higher] Find the intersection points of two graphs, one linear and one non-linear, and recognise that the solutions correspond to the solutions of the combined equation
- [Higher] Calculate the gradient of a straight line given the coordinates of two points
- [Higher] Find the equation of a straight line parallel to a given line; find the equation of a straight line perpendicular to a given line
