# Straight Line Equations (pre-GCSE)

## 10 files11/05/2016

(a) Recap: Know equations of vertical and horizontal lines (e.g. x = 3) and also y = x and y = -x.

(b) Appreciate the conceptual line between lines and their equation (i.e. a line is a set of points that satisfies the equation).

(c) Plot graphs usng a table of values (both linear and quadratic equations).

(d) Find gradient given (i) the equation of the line or (ii) two points on the line. Appreciate gradient gradient is the y-change per unit x change. Includes negative and fractional gradients.

(e) Recognise and use y = mx + c. Find equation of a line given a drawing, and vice versa.

(f) Appreciate that parallel lines have the same gradient.

(g) Determine the x and y intercept of a line.# Laws of Indices (pre-GCSE)

(Used to the Tiffin Year 8 scheme of work)

(a) Know laws of indices for multiplying, dividing, raising a power to a power. Understand negative and zero indices.

(b) Be able to raise a whole term to a power, e.g. (3m^2)^4 = 81m^8.

(c) Be able to raise a fraction to a power, e.g. (3/2)^-3 = 8/27.# Standard Form

(a) Understand why putting numbers in standard form is useful (particularly in Science).

(b) Be able to use the x10^ button on your calculator.

(c) Convert numbers to and from standard form.

(d) Multiply and divide numbers in standard form.
