y = mx + c

Learning Objective:- to plot straight line graphs (grade C) and use y = mx + c (grade B)to find

parallel lines (grade A)

Tracking A

Key words: gradient, y intercept, parallel

Challenge:Which pair of lines are parallel and how do you know?Which pair are perpendicular and how do you know?

Success Criteria

Grade D recognise parallel and perpendicular lines

Grade C plot straight lines from a table of values

Grade B use y = mx + c to plot straight lines

Grade A use y = mx + x to find parallel lines

Grade A* use y = mx + c to find perpendicular lines

Page 3: y = mx + c year11

Using your mini whiteboards...

... Fill in this table

x -1 0 1 2 3

y

y = 2x + 1

Can you plot this line?

Page 4: y = mx + c year11

Use your mini whiteboards and the tables of values to plot

these lines...y = 3x + 2

y = -2x + 1

y = 4x + 2

y = 3x - 1

Page 5: y = mx + c year11

y = mx + cWhat is the gradient and y intercept for

each of these lines?

y = 3x + 2

y = -2x + 1

y = 4x + 2

y = 3x - 1
