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
Up 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
Up 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
Up 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
Up 5
Right 7
pick two points on the line
that are on the graph lines

So when given a line

The slope is
on a graph
Up 5
Right 7
pick two points on the line
that are on the graph lines

So when given a line

The slope is

Slopes can also be negative
Slopes can also be negative
Slopes can also be negative
but for negative slopes
Slopes can also be negative
but for negative slopes
we go down first
Slopes can also be negative
Down 3
but for negative slopes
we go down first
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
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
Slopes can also be negative
So the slope is

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
