Welcome to my page of  helpful hints. I hope that you find my page intresting and informative, Good Luck !!!Enjoy!!!! 
 

~ Solving Linear Equations~

A Linear equation is an equation that can be written in the form ax = b where a and b are constants and a doesn't equal 0.


Examples: Comments:
2x-4x=-5
2x = -5
2       2
x = -2.5
This is the begining equation Combine like terms. Divide by 2 to get the x by itself.Since x is alone now you divide the -5 by 2 and then you have solved the linear equation.


~Solving Literal Equations~

For a Literal Equation you will not be solving for numbers. You are solving for letters. This is used alot in science equations.


 Example:  Comments:
D = RT (solve for T)
R      R
T=D
      R
When you start to solve look and see what it is asking you to solve. In this equation we are solving for T. To get T by itself you must first divide by R. Finally you rewrite your equation to T =....... in this case T=D/R.

~ 3 Types of Equations For a Line ~


Examples: Comments:
Slope Intercept Form:  Y= Mx + B
 Y= 3x + 2
 
In slope intercept the 2 is the y- intercept on a graph. The 3x is the slope of the line.

 
 
Examples: Comments:
Standard Form: Ax +Bx = C
5x + 2y = 7
In this form you have to solve for y in order to graph the line.

 
 
Examples: Comments:
Point Slope Form: Y - Y1 = M (X - X1) M in this equation before the X is the slope of the equation.
