Systems of Equations
The point where two graphs intersect.
What is the point of intersection or solution?
A relation where there are no x-value repeats.
What is a function?
The solution to 2x+5=15.
What is 5?
The standard form of a quadratic equation.
What is ax2+bx+c?
These are all integers, fractions, and terminating/repeating decimals.
What are rational numbers?
The solution to:
y=x+2
y=2x+1
What is (1,3)?
This test is used to determine if a graph represents a function.
What is the Vertical Line Test (VLT)?
The type of line is used when graphing y>3x−2.
What is a dashed line?
DAILY DOUBLE
The name of the graph of a quadratic function.
What is a parabola?
A number that cannot be written as a fraction.
What is an irrational number?
Solve the system using substitution:
y=x+2
y=2x−1
This is the solution to the system.
What is (3,5)?
The set of all possible input values (left to right) of a function (line or parabola).
What is the domain?
The slope of the line y=−4x+7.
What is -4?
The vertex of a parabola represents this point.
What is the minimum or maximum?
This is the point where a graph crosses the y-axis.
What is the y-intercept?
DAILY DOUBLE
The two most common methods used to solve systems.
What are graphing and substitution?
If f(x)=3x+2, this is the value of f(4).
What is 14?
The average rate of change.
What is slope?
The zeros of a quadratic function are the x-values where the graph crosses this axis.
What is the x-axis?
This is the number that appears in front of a variable and indicates how many of that variable there are.
What is coefficient?
The solution to a system of inequalities is not usually a single point. Instead, it is this.
What the overlapping shaded region?
The set of all possible output (bottom to top) values of a function (line or parabola).
What is the range?
The equation of a line with slope 2 and y-intercept -1.
What is y=2x-1?
The quadratic function y=(x−3)(x+2) has these two zeros.
What are x=3 and x=−2?
This property states that changing the order of addition does not change the sum.
For example, a+b = b+a.
What is the Commutative Property of Addition?
