What is a Binomial & Trinomial?
100
Solve the equation.
2x+6=12
x=3

What is a scatter plot?
It is a graph in which the values of two variables are plotted along two axes, the patter of the resulting points revealing any correlation present.
100
Linear or Exponential ?
EXPONENTIAL

2x-4y=24
-6x+4y=-24
(0,-6)
200
What is Domain & Range?
Domain: Independent Variable, is a set of all possible x-values, which will make the function "work" (the number you plug in x to get an output of y)
Range: The range is the complete set of all possible resulting values of the dependent variable (resulting y values we get after plugging in the x values in the equation)

Solve the equation:
-5x+8 = -3x+2
x=3
200
Is this scatter plot positive or negative?
The scatter plot has a positive trend.

Solve the system by elimination. Then CHECK your solution.
-10x+10y=0
-20x+20y=20
No solution.
300
What does it mean to combine "like terms"?
A process used to simplify an expression or an equation using addition and subtraction of the coefficients of terms.
300
Solve the inequality.
3(6x-1) > 18 - 3x
x>1
300
What is a Correlation?
Correlation is made of Co- meaning together and Relation. Correlation is positive when the values increase together, and Correlation is negative when one value decreases as the other increases.

If you have a slope of 4 and a y intercept of 5 what is you linear equation?
Hint: y=mx+b
y=4x+5

What is the equation for slope and what is slope intercept form?
Slope Intercept Form: Y=mx+b
M = Slope
B= Y-Intercept
Equation for Slope: Y2-Y1/ X2-X1

400
Is the scatter plot negative or positive?
Negative

500
What does it mean to "evaluate"?
Substituting a number for each variable and performing the arithmetic operations.
500
An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. Assume the plane continues at the same rate of descent. How high would the plane be after 13 minutes?
4,000 feet
500
What is a line of best fit on a scatter plot?
Line of best fit, is also known as the "Trend Line" on a scatter plot. It is when you have the line as close as possible to all points, and as many points above the line as below.

What is Exponential?
An exponential function is a mathematical function following the form of f(x)=a^x
