3x+2=11
x=3
What are the three rigid transformations?
translations, reflections, and rotations
What do we do with exponents when we multiply and the bases are the same?
Keep the bases the same and add the exponents.
What is slope intercept form?
y = mx + b
How do you know if a set of data is a function or not a function?
if it touches 2 points in the vertical line test OR if each x has only one y
-1/2 x +14 =-6
x=40
What is the one non-rigid transformation we discussed? AND what does the transformation do?
Dilation, increases and decreases the size of a shape. Keeps the shape proportional.
What do we do with exponents when we divide and the bases are the same?
Keep the bases the same and subtract the exponents.
What does the b stand for in
y=mx+b
B represents the y-intercept.
definition of function
a relation (set of data) involving one or more variables in which each x (input) has only ONE y-value (output)
What kind of solution does this equation have?
2x = 2x
infinite solutions
What transformation has taken place here? BE SPECIFIC AND DETAILED.
Reflection across the x-axis.
Simplify.
5^9
What is the slope? What is the y-intercept?
y = 3x - 5
Slope (M) = 3
Y-intercept (B) = -5
Is the following a function?
{(3, 5) (5, 8) (2, 7) (3, 4)}
No, it is not a function. x-value of 3 is repeated. The x value of 3 has two different y values. It would not pass the vertical line test.
Solve for m.
2(m + 4) + 7 = 9m - 13
x = 4
90 degree counter-clockwise rotation around the origin.
Can we have a negative exponent? What do we do if we want to make it positive? (You can use an example to answer this)
Flip it to the bottom...
ex: 6^-7 -----> 1/6^7
Calculate the slope
(0, 25) and (10, 0)
m= -2.5
Is the following a function?
No it is not a function. It doed not pass the vertical line test.
What are the three possible types of solutions for a system of equations?
One solution, no solution, and infinite solutions.
What two transformations occurred to go from triangle A to triangle B:
Reflection over y-axis and then translation up 2 and left 2.

2^5 * 5^4 / 2^3 *5
500
Calculate the slope
(2,3) and (9,7)
m= 4/7
If the graph were rotated 90° counter-clockwise would the relation be a function?
Yes it would be a function.
