~ 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. |
