Graphing
What are all of the type of solutions you can have in a system of equations?
One Solution, Infinite Solutions, or No Solution
What is Substitution used for?
To find the solution in a system of equations
What do both equations in a system need to have in order to eliminate?
Same number, but different sign
Name all of the Transformations.
Translation, Reflection, Rotation, Dilation
Create a line plot for the following information:
Students at Oakdale Middle School wrote and submitted poems for a district-wide writing contest. 8 students wrote one poem, 2 students wrote 2 poems, 5 students wrote 3 poems, 6 students wrote 4 poems, and 10 students wrote five poems.
To be assessed by teacher.
What does a system of equations with one solution look like when graphed?
Intersecting lines
Use substitution to find the solution:
y = 5
2x − 5y = –5
(10,5)
Use Elimination to find the solution:
5x − 2y = –14
–x + 2y = –2
(-4,-3)
What is this asking you to do T<-4,7>?
To translate 4 units to the left and 7 units up
What is the difference between a bar graph and a histogram?
A histogram does not have any gaps in between the bars
What does a system of equations with infinite solutions look like when graphed?
Overlapped lines
Use Substitution to find the solution:
y = –10
–9x + 8y = 1
(-9,-10)
Use Elimination to find the solution:
x − 9y = 4
–x − 2y = 7
(-5,-1)
How many quadrants do you rotate with r270°?
3 quadrants
What does the five-number summary consist of in a box-and-whisker plot?
The median, minimum, maximum, first quartile, and third quartile.
What does a system of equations with no solution look like when graphed?
Use Substitution to find the solution:
y = –6x − 2
y = –3x − 5
(1,-8)
Use Elimination to find the solution:
–3x + y = 12
–3x + 2y = 6
(-6,-6)
What do you use equidistance for when completing a reflection?
Find the median in the following data set:
7, -2, 1, 0, -4, 6, 11, -2.5
0.5
Graph the following system and state the solution:
y = 2x + 4
y = 6x - 1
(1, 6)
Use Substitution to find the solution:
x + 8y = 1
x + 3y = 6
(9,-1)
Use Elimination to find the solution:
–x − 3y = –2
–3x − 3y = 18
(-10,4)
What is the first thing to remember when completing a sequence of transformations?
To read the transformations form right to left!
Find the mean and range in the following data set:
2,6,9,1,2,4
Mean is 4
Range is 8
