What is an exponent?
An exponent shows us that we need to multiply a number times itself. It can be positive or negative, whole or a fraction.
100
What is slope?
What is y-intercept?
Slope is the rate of change/rise over run/ M. It tells us how much Y will increase/decrease every time X goes up 1.
Y-intercept is our initial value/Y when X=0/B. It tells us what Y is when we are starting, if we are graphing a real-world problem.

Define independent variable. Give an example.
Define dependent variable. Give an example.
X. The variable that changes on its own. For example, time or age, etc.
Y. The variable that changes BECAUSE OF the independent variable. For example, distance, height, etc.

- c < 3
- c > 3
- c ≤ 3
- c ≥ 3
3. c ≤ 3

What is the difference between volume and surface area?
Volume is the space inside a shape.
Surface area is the faces/outside of the shape

Is the point (8, 3) a solution to the equation y = -2x + 7?
No.
3 = -2(8) + 7
3= -16 + 7
3 = -9

If the area of a circle is 81π in², what is its diameter?
- 81 in
- 9 in
- 3 in
- 18 in
Area of a circle = pi * r2
4. 18 in
(diameter = 2 radius!)

Can we simplify these expressions? Write Yes or No for each.
1. 53 x 54
2. 62 x 79
3. 42 x 32
1. Yes - they have the same base
2. No
3. Yes - they have the same exponent

A line has a slope of -5/3 and a point at (-2, 6). Write the equation of this line in y=mx+b form
y = mx + b
6 = -5/3 (-2) + b
6 = 10/3 + b
6 - 10/3 = b
8/3 or 22/3= b
y = -5/3x + 8/3

1. They have 3 sides and three angles
2. They have a 90 angle
3. The longest side is called the hypotenuse
4. You can find a missing side using a2+b2=c2
5. The area = 1/2bh
6. ...

Deann flips a coin. Then DonDon spins a spinner that has four sections (see below)
What is the probability that Deann gets heads AND DonDon lands on blue?
heads = 1/2
blue = 1/4
heads AND blue = 1/2 * 1/4 = 1/8

Describe the transformations that occurred to go from the blue triangle to the green triangle.
The triangle was REFLECTED across the Y-axis (line x=0). Then it was TRANSLATED down 8 units.
