Mathematics Relationships (National 4)

1	Applying algebraic skills related to linear equations
1.1	Drawing and recognising a graph of a linear equation	Draw using a table of values or chosen values of x For y = mx +c, know the meaning of m and c Recognise and use y = a, x = b
1.2	Solving linear equations	ax + b = c ax + b = cx + d
1.3	Changing the subject of a formula	Change the subject of the formulae to x: G = x + a T = x/c E = wx + k

2	Applying geometric skills related to sides and angles of shapes
2.1	Using Pythagoras’ theorem	given measurements given co-ordinates
2.2	Using a fractional scale factor to enlarge or reduce a shape	Linear, non-rectangular shape
2.3	Using parallel lines, symmetry and circle properties to calculate angles	Combination of angle properties associated with: Intersecting and Parallel lines triangles and quadrilaterals Circles :angle in a semi-circle relationship between tangent and radius

3	Applying trigonometric skills related to right-angles triangles
3.1	Calculating a side in a right-angled triangle	Given a side and an angle
3.2	Calculating an angle in a right-angled triangle	Given two sides

4	Applying statistical skills related to representing data
4.1	Constructing a scattergraph (2.6 Managing Finance and Statistics)	Given a set of data
4.2	Drawing and applying a best-fitting straight line (2.7 Managing Finance and Statistics)	The line should have roughly the same number of data points on either side Use the line of best fit to estimate one variable, given the other
