100
What is the directionality of this graph? How do you know? Is the slope positive or negative?
What is increasing because the line is going up, and the slope is positive.
100
y = 3/x - 9 Is this equation linear or nonlinear? Why?
What is nonlinear because x cannot be in the denominator.
100
What are the 2 main equations for lines?
What is y = mx + b and Ax + By = C.
100
Is 2/3 pi rational or irrational and why?
What is irrational because pi goes on forever.
100
Write 3 x 10-5 in standard form.
What is 0.00003.
200
What is the equation of this line?
What is y=x+2
200
Is this data a relation, function, both, or neither? Why?
(3, 4), (5, -4), (7, 4), (-4, 8)
IT is both because no x repeats.
200
Solve.
4 - (3x - 5) + 7x = 2(2x + 3)
What is no solution.
200
What is the cube root of 512.
Rational or irrational?
What is 8 and rational.
200
Write 2,408.7 in scientific notation.
What is 2.4087 x 103.
300
What is the equation of the line? Also, write a line parallel to it.
What is y=-3x+1.
and y = -3x + any b other than 1
300
Function, relation, both, or neither. Why?
What is no because 1.2 has more than 1 output.
300
Solve.
4x - 5y = 12
3x - 5y = 6
What is (6, 2.4).
300
Approximate the square root of 95 to the nearest tenth.
Is the square root rational or irrational?
What is 9.7 and irrational.
300
Simplify.
(x6*x10)/(y-2)3
What is x16y6.
400
Using the same y-intercept, write an equation that would be nonlinear.
What is y=x2- 2.
400
Linear or Nonlinear?: (4, -1), (5, -6), (2, 14), (4, 4)
Show work as proof.
Function, relation, both, or neither? Why?
It is linear because of same slope but only a relation because 4 cheats.
400
What does it mean if an equation has infinite solutions?
What if a system has infinite solutions?
In the equation, all values will work to be substituted in.
In the system, the 2 lines are the exact same.
400
What 2 numbers is the square root of 395 between?
What is 19 and 20?
400
How many times smaller is 4 x 108 than 8 x 105?
What is 500 times smaller.
500
What is the slope for this graph and what does it mean? 
What is 6 inches per 3 lbs or the spring is 2 inches per every pound.
500
What is the linear equation of the line containing these points (put in slope-intercept form):
(3, 4) and (-5, 8)
What is y=-1/2x + 5.5.
500
Solve.
8x - 3y = 10
y = 2x
What is (5, 10).
500
The cube root of 125 times three is_________ the square root of 48 plus the square root of 62.
less than, greater than, or equal to? (Show work.)
What is greater than because 15 is greater than 6.9 + 7.9=14.8.
500
(14x3y15z-4)/(7x3y7)
What is 2y8/z4.
