Distributive Property
What is the distributive property?
When you share a number or a variable with the rest of the equation or expression.
What is slope?
rise over run, how steep the line is on the graph.
What is a solution to an equation?
An answer or a possibility for an "x" or variable in the equation
What does an equation have that an expression DOES NOT have?
Equation has an equal sign... expressions do not.
What are the parts of a box plot?
Minimum, Maximum, Median, 1st Q, 3rd Q,
Solve:
2(2+3)
10
What is the formula for slope?
y2-y1 / x2-x1
What is the solution to the equation:
2 + x = 7
x = 5
How do you know an expression is simplified?
When you cannot combine terms any longer.
How do you find the Interquartile Range? (IQR)
3rd quartile MINUS 1st quartile
Solve:
x(2+5)
7x
Describe a positive slope, negative slope, an undefined slope, and a zero slope.
Have the students draw it.
Positive goes up from left to right.
Negative goes down from left to right.
Undefined slope is a vertical line.
Zero slope is a horizontal line.
What is the solution:
2x + 7 = 17
x = 5
Simplify the expression:
z - 1 + 4
z + 3
Domain: X values
Range: Y values
Solve: a (b + c)
ab + ac
Label the parts of the formula:
y = mx + b
m is slope
b is y-int
What is the solution:
14x - 12x + 2 = 10
x = 4
Simplify the expression:
a^2 - 1 + 4
a^2 + 3
Create a box plot for the following data:
76, 70, 72, 71, 69, 78, 74
Check student papers
Solve:
(2)6a + 2b = 2
12a + 4b + 4
What is the equation of the line passing through point (-3, 1) with a slope of 2.
y = 2x + 7
OR
2x - y + 7 = 0
What is the solution:
x/3 - 6 = 9
x = 45
Simplify the expression:
9y + 6 - 7y - 3
2y - 3
What is the difference between a scatter plot and a bar graph?
Scatter plots have points all over the graph, they do not create a line.
A bar graph do not have points, the data is shown by the height of the bars.
