y = mx + c
y = -2x + 5
y-intercept
gradient
Drawing linesDraw the line: y = 3x – 2
If you finish quickly: y = 3x + 6
How?Make a table of values
OR
Mark the intercept, then movealong 1 and up m to find more points
GCSE Exam Question – Straight Line Graphs
Remember:Parallel lines have the same gradient
y = ½x + ?
y = ?x + 1
