Let's Get Real
The set of rational and irrational numbers.
What is the set of Real numbers?
The point, or ordered pair, where two lines intersect on a graph.
What is the solution?
This property has a sum of 0.
What is the additive identity?
This is where the line crosses the y-axis.
What is the y-intercept?
The property that is used in step one when solving
2(x - 4) - 3x = 27.
What is the distributive property?
{0,1,2,3...}
What is the set of whole numbers?
Graphically, elimination and substitution.
What are the three ways to solve a system of equations?
The operations that "work" for the commutative property.
What are addition and multiplication?
This is the change in y over the change in x.
What is the slope?
The property that can be used to solve the following equation: 2/3x = - 4
What is the multiplicative inverse or the division property of equality?
I can be a fraction, decimal, whole number, integer, or natural/counting number.
What is a rational number?
y= 5x -7
-3x - 2y = -12
What is (2,3)?
The multiplicative inverse of -8.
What is -1/8?
The equation of a line that has a slope of -1 and passes through the point (-2,3).
What is y = -x + 1?
Explain two ways you can solve: 20 = 5(−3 + x)
What is distribute the 5 or divide both sides of the equation by 5?
I'm a non-terminating, non-terminating decimal.
What is an irrational number?
Solve graphically:
y = 2x - 4
y -2x = 5
What is no solution?
Look at Ms. Eilers work:
Original problem: -12 x 1/3 x 5 x -3
Line 1: -12 x 1/3 x -3 x 5
Line 2: -12(1/3 x -3) x 5
Line 3: -12(-1) x 5 = 12 x 5= 60
The properties that were used in lines 1 and 2, respectively.
What is the commutative property and the associative property?
The equation of a line that passes through the points (-3,-1) and (2,-2).
What is y = -1/5x - 8/5 ?
The solution to -10n + 3(8 + 8n) = -6(n-4)
What is 0?
All the sets of numbers that -1.5 belongs in.
What is a Real number and a Rational number?
-5x - 8y = 17
2x - 7y = - 17
What is (-5, 1) ?
The following is undefined when x is...
4/ 3x - (-9)
What is -3?
The equation of a line that passes through the point (-1, 1) and has the same slope as y - 4x = 8.
What is y = 4x + 5?
The solution when 2(x +10)−17 = 5 + 2x − 2 is solved for x.
What is all real numbers or infinite solution?
