#### Transcript of Recognising Graphs

Recognising Graphs
Starter
Describe the graphs given by:

(a) y = 3x - 4
(b) y = 3x + 4
(c) y = 4 - 3x
(d) y = -4 - 3x
Example
Find the equation of this graph
Example
L.O. - Identify the type of graph and match graphs to equations.
Starter
Describe the graphs given by:

(a) y = 3x - 4
(b) y = 3x + 4
(c) y = 4 - 3x
(d) y = -4 - 3x
Straight line with gradient of 3 crossing the y-axis at -4
Straight line with gradient of 3 crossing the y-axis at 4
Straight line with gradient of -3 crossing the y-axis at 4
Straight line with gradient of -3 crossing the y-axis at -4
Find the equation of this graph
Example
Find the equation of this graph
y = x + 1

Example
Find the equation of this graph
y = x - 4

Activity
Match the graphs to the equations
y = -x

y = -x + 1

y= tan x

y = x + 1

y = x - 4

y = sin x

y = -4 - x

y = 4 - x
