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

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

Run +7

pick two points on the line

that are on the graph lines

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

and then right

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
