# 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.# 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.# Compound Measures

(a) Solve simple problems involving (average) speed, distance and time.

(b) Solve problems involving density, mass and volume (which could include volumes of prisms and cuboids).

(c) Solve more complex problems involving speed, distance and time, including with multiple phases of a journey, or an algebraic element.
