MathWhat do you know about math

equations?

EquationWhen using math equations what do you

deal with? Give an example.Slope, linear inequality, point-slope

Here’s an equation.

Here’s an equation: y=2x-5The 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.

How to solve an equation?

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.

Things you want to use while in an given equation. 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

Y=mx+b

X 8 6

B 2 9

Y=mx+b M=6+-9 = -3 8-2 4 Your slope is: -3 4That’s your slope!!

Linear inequality

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!!

Steps to linear equality

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)

Example

1. Y < + 62. 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.

solve Y=-8< + 6, y=6 > - 8 8 7 6 5 4 3 2 1 0 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8

Point-slope

Tell me what you know about point-slope ?

I know that it’s a certain formula that you will use while doing this particular assignment.

It is call the point-slope formula. This is what it looks like.

Y-y1=m(x – x1) You will use that with the slope form. Its together Wow how neat!!

point slope, example:

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

Example 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

Questions!!!

What is the slope formula?

The slope formula is y=mx+b

What do you look for in an linear equality?

You determine whether or not its an dash or solid

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

What is the formula for point-slope form?

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

The end!!
