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
