what is a linear inequality?
Front
It is an equation with a <, >, < or =, > or = in the place of the =.
Back
in y = mx + b, "m" stands for?
Front
slope
Back
what is the x-intercept?
Front
the point where the graph crosses the x-axis. It has the coordinates (x, 0)
Back
graph of a quadratic function
Front
Back
graph of a linear function
Front
Back
dependent variable
Front
the OUTPUT or RESULT in a situation or problem. It's the variable YOU CANNOT control. It's the Y variable. In a equation, its the variable BY ITSELF on one side of the = sign.
Back
Where are the solutions of a quadratic function?
Front
at the x-intercepts. They are also known as zeros and roots.
Back
How do you MULTIPLE exponents of like variables?
Front
ADD them
Back
other names for "x"
Front
domain, independent variable, input
Back
What are "like terms"?
Front
mathmatical terms that have the SAME variables raised to the SAME exponents.
Back
other names for "y"
Front
range, dependent variable, output
Back
How many solutions can a system 2 equations have?
Front
1) no solutions, if the lines are parallel and have the same slope. 2) one solution, if the lines intersect at one point. 3) infinite many solutions, if the two equations are the same and touch each other everywhere.
Back
domain
Front
set of all of the possible x-values. INPUTS
Back
what is the linear parent function?
Front
y = x
Back
graph of an inverse function
Front
Back
what is the y-intercept?
Front
the point where the graph crosses the y-axis. It has the coordinates (0, y)
Back
changing the "b" in the slope-intercept form of the equation of a line changes what?
Front
moves the line up or down the y-axis.
Back
What is a quadratic equation or function?
Front
an equation of function that has "x-squared" as its highest order exponent. Example: 2x^2 + x + 3
Back
changing the "m" in the slope-intercept form of the equation of a line changes what?
Front
the steepness of the line
Back
ordered pair
Front
the x and y coordinates of a point on the coordinate plane
Back
words for ">"
Front
more than, is greater than, is larger than, above
Back
independent variable
Front
the INPUT or CAUSE in a situationor proble,m. It's the variable YOU CAN control. It's the X variable.
Back
What is a system of equations?
Front
2 or more equations graphed on the same coordinate plane
Back
graph of exponential growth function
Front
Back
What is Direct Variation?
Front
y = mx, or y = ax, or y = kx. m, a, or k is just the coefficient in front of the x. They are also the SLOPE of the direct variation line. Direct variation lines have a y-intercept ot (0, 0)
Back
what slope does a HORIZONTAL line have?
Front
slope = 0
Back
How do the slopes of perdendicular lines compare?
Front
They are opposite and fraction is flipped. Example: lines with the slopes -2 and 1/2 are perpendicular.
Back
How do you DIVIDE exponents of like variables?
Front
SUBTRACT them
Back
discreet function
Front
data appears as individual point on a graph. Whatever is being graphed cannot be broken down in to smaller pieces......like stairs or people.
Back
how is slope important for linear equations and lines?
Front
linear equations and lines have CONSTANT slopes. The slope is the SAME all the way up and down the line.
Back
How do the slopes of parallel lines compare?
Front
They are the same
Back
How do you combine like terms?
Front
Add their coefficients.
Back
relation
Front
set of ordered pairs
Back
function
Front
special relation where each x-value is paired with ONLY ONE y-value. (x-values DO NOT repeat, it passes the vertical line test)
Back
What is the SOLUTION of a system of equations?
Front
where the lines touch or cross
Back
range
Front
set of all the possible y-values. OUTPUTS
Back
graph of exponential decay function
Front
Back
variable
Front
NOT A NUMBER. A letter or symbol that stands for a number. Variables vary or change
Back
vertical line test
Front
a relation is a function and passes the vertical line test if when a vertical line is drawn through the graph, it touches the graph only ONE time.
Back
What is a line of best fit?
Front
A line drawn through the points on a scatterplot to estimate the best line through the data.
Back
in y = mx + b, "b" stands for?
Front
the y-intercept
Back
continuous function
Front
data appears as a smooth curve on a graph. Whatever is being graphed can be broken down in to smaller pieces......like time.
