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.

Back

What is the "rate of change" on a graph?

Front

Slope

Back

words for "<"

Back

coordinate plane

a plane formed by 2 perpendicular lines called axes

Back

what slope does a VERTICAL line have?

Front

undefined slope

Back

What is Inverse Variation?
