LINEAR EQUATIONS
SLOPE OF ANY HORIZONTAL LINE
ZERO
Simplify (4x)^0

SLOPE-INTERCEPT FORM of a linear equation
y = mx + b ?
10^-2
1/100 or 0.01 ?
-7X + 5 < - 9
X > 2
How you can tell (without graphing) that there is NO SOLUTION to a system of equations
the SLOPES are the SAME
How to find the PERCENT CHANGE
What is DIVIDE the DIFFERNCE by the ORIGINAL amount
Slope of any VERTICAL LINE
UNDEFINED
Simplify (7ab)^2
49(a^2)(b^2) ?
(X + 5) / 6 > - 4
X > - 29
How many solutions a system of equations has when the graph shows INTERSECTING lines
ONE
HOW PROPORTIONS ARE SOLVED.
CROSS MULTIPLICATION
POINT SLOPE FORM OF A LINE
y - y1 = m (x - x1) ?
Simplfy (5x^2)^3
125x^6?
28 < 4 - 4X
X < - 6
the number you could multiply the FIRST EQUATION by so that you will ELIMINATE the X'S when you add the equations together. -3X + 5Y = 20 . -12X - 4Y = 0
-4
35 is 50% of this number
70
definition of SLOPE
rise over run, or rate of change
(4x^5)(3x^7)
12x^12?
| X | > 3
X > 3 or X < -3
When the graph of two equations looks like this, there are INFINITELY MANY SOLUTIONS
ONLY ONE LINE (they intersect everywhere)
75 is this percent of 50
