So when given a line

So when given a line

So when given a line

on a graph

So when given a line

on a graph

So when given a line

on a graph
pick two points on the line
that are on the graph lines
these points
aren't on the
graph lines

So when given a line

on a graph
pick two points on the line
that are on the graph lines
so I wouldn't use them

So when given a line

on a graph
pick two points on the line
that are on the graph lines
so I wouldn't use them

So when given a line

on a graph
pick two points on the line
that are on the graph lines

these points are

So when given a line

on the graph lines
on a graph
pick two points on the line
that are on the graph lines

these points are

So when given a line

on the graph lines
so I can use them
on a graph
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

on a graph
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

on a graph
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

on a graph
Rise +5
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

then right
on a graph
Rise +5
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

then right
on a graph
Rise +5
pick two points on the line
that are on the graph lines
then count up or down,

So when given a line

then right
on a graph
Rise +5
Run + 7
pick two points on the line
that are on the graph lines

So when given a line

The rate of change is
on a graph
Rise +5
Run + 7
pick two points on the line
that are on the graph lines
The rate of change  is

So when given a line

on a graph
Rise +5
7
5
Run +7
pick two points on the line
that are on the graph lines

Rates of change can also be negative
Rates of change  can also be negative
 Rates of change can also be negative
Rates of change can also be negative
Rates of change can also be negative
but for negative 
Slopes can also be negative
but for negative Rates of change 
we go down first
Rates of change can also be negative
Rise -3
but for negative Rates of change 
we go down first
Rates of change can also be negative
Rise -3
but for negative Rates of change 
we go down first
and then right
Slopes can also be negative
Down 3
but for negative slopes
we go down first
and then right
Slopes can also be negative
Down 3
Right 2
but for negative slopes
we go down first
and then right
So the Rate of change  is 
Slopes can also be negative
Down 3
Right 2

but for negative slopes
we go down first

You can also find the Rate of change using the equation
You can also find the Rate of change using the equation
y = 2x + 7
You can also find the Rate of change using the equation
y = 2x + 7
If the y is by itself
y by itself
You can also find the Rate of change using the equation
y = 2x + 7
If the y is by itself
You can also find the slope using the equation
y = 2x + 7
If the y is by itself
then the number by x
number by x
You can also find the slope using the equation
y = 2x + 7
If the y is by itself
then the number by x
You can also find the slope using the equation
y = 2x + 7
If the y is by itself
then the number by x
is the slope
2 is the slope
You can also find the slope using the equation
y = 2x + 7
If the y is by itself
then the number by x
is the slope
You can also find the slope using the equation
When the y is by itself
y = 2x + 7
If the y is by itself
then the number by x
is the slope
You can also find the slope using the equation
When the y is by itself
y = 2x + 7
this is called slope intercept form
If the y is by itself
then the number by x
is the slope
You can also find the slope using the equation
When the y is by itself
y = 2x + 7
this is called slope intercept form
If the y is by itself
then the number by x
is the slope
You can also find the slope using the equation
When the y is by itself
y = 2x + 7
this is called slope intercept form
If the y is by itself
then the number by x
is the slope
slope intercept form
What is the Rate of change?
y = 2x +17
