Objective
1. Recognize a linear equation connecting two variables: y = mx + c where m and c are real numbers
2. Plot a straight-line graph of a given equation
3. Calculate the gradient of a straight line from its graph or given two points on the line
4. Recognize the equation and know the gradient for horizontal and vertical lines: x=k and y = c, where k and c are real numbers
5. Find the y-intercept for any straight line from its graph
6. Recognize the equation of a straight line in the form y=mx+c, and use this to state the gradient and the y-intercept for any straight line

8. Calculate midpoint of a line
9. Use distance formula when given two points to calculate to find the distance between them (same as finding the length of a line)
10. Identify parallel, perpendicular lines and perpendicular bisectors write their equations
11. Analyze y=mx+c by using the values of m and c to sketch the graph
12. Solve linear inequalities
