__﻿ ﻿Mr. Hands Linear Equations Rap: __ y=mx+b, it's a linear equation between you and me. Where "m" is the slope and "b's" the y-intercept. If you think I'm jokin', show me some respect.

If they give you the "m" and they give you the "b" put it into the equation and then you will see.

If they give you the slope and they give you a point, Put the "y" in for "y", the "m" in for "m", put the "x" in for "x" and the find "b" Then you"ll have all that's nesaccary

And if they give you two points to run, find the slope and pick one.

 What do you do if it's parallel? The the slope is the same, dude you ain't got no game.

And if it's perpendicular, then you flip it, reverse it. frpfrepreferferperfer

__Websites __ -This website helped me alot with learning and memorizing y=m(x)+b, slope, and the different kinds of lines: __<span style="color: #000000; font-family: Georgia,serif; font-size: 180%;">[] __ <span style="color: #000000; font-family: Georgia,serif; font-size: 180%;">-This is an online flashcard set for linear equations:

 * <span style="color: #9813bb; font-family: Georgia,serif;">Slope <span style="color: #000000; font-family: Georgia,serif;">: A comparison between the change in Y and change in X (rate of change).
 * <span style="color: #736ae9; font-family: Georgia,serif;">X-intercept :<span style="font-family: Georgia,serif;"> An ordered pair where a graph crosses the x-axis (Y=zero).
 * <span style="color: #85dda6; font-family: Georgia,serif;">Y-intercept :<span style="font-family: Georgia,serif;"> An ordered pair where a graph crosses the y-axis (X=zero).

<span style="font-family: Georgia,serif;">m= slope <span style="font-family: Georgia,serif;">b= y-intercept (starting point)

__ Standard Form To Slope Intercept Form __ Example; 4x+5y=15 first you would subtract 4x from each side so you can get Y on the side by itself. -4x -4x __5y__ =- __4x+15__ second you would divide each side by 5 so all you would have left would be Y. 5 5
 * 1. move the X term to the other side of the equal sign
 * 2. divide by the coefficient of Y

y= _ __4x__ + 3 and last you would get your answer by doing the first two step. 5

__ Slope Intercept Form to Standard Form __


 * =====Multiply **//__EVERYTHING__//** by the greatest common denominator=====
 * Move the X term to the other side of the equal sign

__Example;__ y=_ __5 x__- 4 3 3y= - 5x- 12 5x+ 3y= -12
