Finding the
slope of a line
Find the slope of the line in the graph
below:
First you need to plot two points on the line.
For example I chose the two points (0,3) and (4,1)
Plug in the two points into the slope formula
m= (y2y1) / (x2x1)
0,3 4,1
m= (1
uadratic Equations
Example:
2x+3x5=0
First make sure the equation is in standard form
Standard form is:
ax+bx+c=0
Then you need to identify what a, b, and c are:
a=2
b=3
c=5
Next apply the quadratic formula to solve for x:
x=1, 5/2
Solve System of Equations by
Substitution
Example:
2x=4y
5x+3y=10
First you must solve for x or y in the first
equation
2x=4y
y+2x=4
Y=2x+4
Now that we solved for y plug 2x+4
in for y in the second equation
5x+3y=10
5x+3( 2x+4)=10
5x6x+12=10
x+12=1
Solving a system by
graphing
Before you begin to graph you must decide if the ordered pair is a solution of a system
For example:
(4,3)
X+4y=8
3x+2y=6
To know if this order pair is a solution you will need to plug the ordered pair into both equations

Factoring
GREATEST COMMON FACTOR
To factor a number means to write the number as the product of
two or more numbers
For example we will factor the number 12:
12= 6x2
