All 4 different Transformations used to move shapes in a coordinated plane.
What is Translation, Rotation, Reflection, and Dilation
Formula for slope-intercept form AND tell me what each letter represents
Y- y value
X-x value
M-slope
B- y-intercept
4x − 8 = 2x + 8
x =8
10-6 x 10-4

The Pythagorean Thereom
a^2 + b^2 = C^2
What is the difference between similar and congruent shapes?
Similar are either the same shape OR size, not both. Congruent shapes are the exact same shape and size.
What is the slope formula?
m= y2-y1/ x2-x1
4(c−3)+2=2(c+5)
c =10
(55)-5
(52)9
5-43
a=34 b=12
What is the length of the missing side?
C=
Describe a series of transformations to get shape A directly over shape B.
Rotate counterclockwise 90, translate it to the right 4 spaces
Or
Rotate is clockwise 270, translate it to the right 4 spaces
Find the slope:
(4,3) and (8, 18)
15/4
Solve using substitution
y=3x+2
y=−2x+7
( -7, 21)
Write as a positive Exponent

c= Square root of 105.79
If an isosceles triangle has a side length of 5, 5 and 7 and we increase it by a scale factor of 7. What are the new side lenths?
35, 35, 49
Without calculating, do you expect the slope of the line (1,11) and (8,2) to be positive or negative?
The y values are decreasing Or 2-11 will result in a negative number which makes a negative slope
Solve using substitution
y= 3x
x= -5y+64
( 4, 12)
2.63 x 103 + 3.7 x 102
3 x 103
Determine the converse using the Pythagorean Theorem
Yes, it is a right triangle
Describe a series of translations to get shape B over top of shape A.

A.Write an equation for the line
B. How many months will it take the plant to reach 72 inches?
a. y=5x + 12
b. 12 months
Describe what a graph would look like if an equation has one solution, no solutions, and infinite solutions.
One solution: Meets at one exact point
No solution: Two parallel lines
Infinite solutions: exact same line
