Here’s an equation: y=2x-5

The name of this equation is slope intercept form. The formula for this

equation is y=mx+b. your b is your y-intercept. You m is your slope. Your y

is just the y-axis on a graph.

When you are dealing with equations, you are finding your slope + y-intercept. So you can plot on your graph. Your graph will come up after you find your slope and y-intercept.

Its very important that you use certain items to help you find and get your equation.

When finding your equation you want to make a table.

A table will help you find you table.

You want to use tables.

Find your slope + y-intercept.

Example: y=mx+b.

What is your slope and y-intercept

Well to find the answer..you would use your..table

x 8 6

b 2 9

X 8 6

B 2 9

Y=mx+b

M=6+-9 = -3

8-2 4

Your slope is: -3

4

That’s your slope!!

When you use linear inequality, you find the following: solid/dash or shade below/above

If your linear inequality is solid it will look like this > if it’s a dash it will look like this >

You will determine whether or not its shaded below if your y is less, if shaded above your y is greater

You will have three steps to follow!!

1. Determine whether your linear inequality is a dash or solid

2. Then, determine whether or not you will shade below or above

3. Last step, is check your answer!!(graph)

1. Y < + 6

2. Y > - 8

What are your answers to these two problems of linear inequalities

Number one is a solid because its equal to, it’s a shaded below because its less than

Number two is a dash because its equal, it’s shaded above because your y is greater.

Y-y1=m(x – x1)

You will use that with the slope form.

Its together

Wow how neat!!

Here’s an example of point slope

6 and (6,4)

The step are very easy

All you do is place the m with the slope

Then replace y1 with the y-intercept

And you will place the x1 with the x-intercept

Slope 6, and (6,4)

Y - y1=m(x - x1)

Y - y1=6 (x – x1)

Y – 4 =6 (x – 6)

6 * 6 = 36= 36

1 1 1

Y – 4 =6 x – 6

+4 + 4

y =6x -2

The slope formula is y=mx+b

You determine whether or not its an dash or solid

You have to determine whether or not it is shaded above or below

The formula for the point-slope form is y-y1=m(x-x1)
