A _________is usually a letter that represents a number.
What is a variable?
100
Write an algebraic expression for "the quotient of an unknown number, x and 42."
What is x/42?
(it can be a fraction; x is numerator & 42 is denominator OR they can use the division sign between x and 42)
100
An equivalent equation for 5x + 2x = 35
What is 7x = 35?
(NOTE: you must simplify by adding like terms)
100
On the coordinate graph, the horizontal line represents which axis?
What is the x-axis?
100
The value of y in the IV quadrant.
What is negative?
200
The variable in this expression, 14y+7
What is y?
200
Write an algebraic expression for x pencils added to 45 pens.
What is 45 + x (or x + 45)?
200
On the coordinate graph, the y-axis represents which variable, the independent or the dependent variable?
What is independent?
200
The area of a coordinate graph used when plotting (-3,4).
What is quadrant II?
200
The process for plotting the point (-4,-2) from the origin.
What is go to the left 4 spaces, then down 2 spaces and plot a point.
300
The name given to the number in front of the variable?
What is the coefficient?
300
Write an algebraic expression for 5 more than a number times 6.
What is 6x + 5?
(variable can be a different letter)
300
It is a mathematical statement that says two expressions are equal. For example: 3x + 8 = 32
What is an equation?
300
The area of the coordinate graph used to plot the point
(4,-3).
What is the fourth quadrant (or quadrant IV)?
300
The direction of a line when the equation is y = 4
What is horizontal?
(REMEMBER: y has to be 4 at every point)
400
The operation when a number is next to a variable, for example -34b.
What is multiplication?
400
Write an algebraic expression for 10 less than 5 times a number.
What is 5x - 10?
(variable can be a different letter)
400
The equation to find the original amount of money in Jenny's bank account when she deposits 40 dollars and her balance is now $200.
What is x + 40 = 200?
or
What is 200 - 40 =x
400
In an ordered pair, (coordinate point), this variable comes second.
What is y?
400
The direction of the line when the x = -3
What is vertical?
500
Solve -10x when x = -9
What is 90?
500
Write an algebraic expression for 6 less than twice a number, x.
What is 2x - 6?
500
The equation for the cost of a cab ride is $5.50 plus 25 cents per mile.
What is y=.25x + 5.50?
(NOTE: you need to change the 25 cents into decimal form AND keep in mind that the 5.50 dollars is a "flat fee" you are paying JUST to ride in the cab)
500
The point on the coordinate graph where the x-axis and
y-axis intersect.
What is the origin?
OR
What is (0,0)?
500
The range of (-2,-3), (0,4), and (4,5).
What is (-3, 4, 5)?
NOTE: Remember, input values = domain & output values = range.
