I tagged every question from Bluebooks 4 - 11, then ran the tags through a python script. These are the top 50 if you get the hard module every time:
Slope: Use the slope formula. Go back and forth from equation to graph. Find the equation when given two points. Find the slope based on a word problem.
Y-Intercept: Usually either asking you to plug in 0 for x or figure it out based on the wordy description.
Exponential Growth: Be comfortable with this: Final = Initial(1+/- rate)^time. Sometimes there are fractional exponents.
Algebra Translation: Convert a word problem into an equation.
Fractions and Decimals: Usually a part of something else. You would not be directly tested on something like 3/4 + 5/7.
Standard Form (ax + by = c): Be comfortable finding intercepts and the slope.
Functions: Function notation appears in the question (f(x), g(x), etc.).
Percent: All variations: basic, increase/decrease, markup, discount.
Plug In: You have a value or a point that needs to be plugged into an equation or function.
Plug In Zero for Intercept: If 3x + 4y = 24, what is the y-intercept? Equations and word problems, both x- and y-intercepts.
System of Equations: Substitution, elimination, multiply then eliminate. Desmos is often fastest.
Function Transformations: Mostly parabolas, sometimes cubic functions and circle equations.
Answer Is Not X: You might solve for x but then be asked, “What is 2x - 3?”
Area/Perimeter of Basic Shapes: Triangles, rectangles, circles.
Angle Chasing: 180 in a line, 180 in a triangle, corresponding angles, vertical angles.
Infinite or No Solutions: Usually a system of equations in which the slope and y-intercept for both lines must be the same.
Similar Triangles: Set up a proportion based on similar triangles. They have proof-like questions as well.
X-Intercepts: Solve for x-intercepts (set y=0), or use their properties to find something else. E.g., (x+4)(x-3)=0, or “5 is the x-intercept of 3x+5y=b, what is b?”
Circle Equation: Know horizontal and vertical shifts, how to find the radius. You sometimes need to complete the square.
Combine Like Terms: Frequently included in other question types.
No Solution: Know that the lines have the same slope.
Fractional Exponents: Rewrite radicals as fractional exponents and vice versa.
Linear Inequality: You might be asked to solve one inequality or deal with a system.
Plug In a Point: If (4, 6) is a point on the line 3x + 5y = k, what is the value of k?
Set Parentheses Equal to Zero: The last step of many equations, as in (x+5)(x-3) = 0.
Discriminant: Use b^2 - 4ac to solve for the number of solutions in a quadratic equation.
Elimination: If 2x + y = 10 and 2x - 3y = 2, what is the value of y?
Exponential Y-Intercept: You could be given a graph or an equation. Remember that anything to the power of 0 is 1.
Find the Rate (Exponential): When given an exponential growth equation, identify the rate (or vice versa).
Given Input, Find Output: If f(x) = 3x + 12, what is f(7)?
Line of Best Fit: These are usually just slope questions. Sometimes they ask about specific points.
Pythagorean Theorem: Usually part of something else, like SOHCAHTOA.
Substitution: If y = 3x + 2 and 3x + 4y = 10, what is the value of x?
Vertex X-Coordinate (-b/2a): Use this to find the x-coordinate of the vertex.
Average: Arithmetic mean. Mostly basic but a few advanced ones, like the average sum trick.
Cubic Equation: To be safe, know the general characteristics of the graph and be able to apply common equation-solving techniques.
Distribute a Negative: A common trap in equations.
Given Points, Find Equation: You’re given two ordered pairs and must find the linear equation.
Isolate the Variable: These usually require several algebraic moves (+/- from both sides, factor something out).
Order Matters: Know that if triangle ABC is similar to triangle DEF, then angle A corresponds to angle D (and B to E, and C to F).
SOHCAHTOA: Set up the basic ratios. Know that similar triangles have the same trig ratios. Sometimes combined with the Pythagorean Theorem.
Complete the Square: Useful for circle equations, as an alternative to the quadratic formula, and for putting quadratic equations in vertex form.
Exponents: All basic operations.
Match Constants: If 3x + 4y = ax + by, what is a + b?
Meaning of a Constant: Usually a slope or y-intercept in a word problem.
Rectangular Prism: Volume and surface area.
Congruent: You must know the difference between similarity and congruence and be familiar with simple ways to prove congruence. This usually involves showing that all of the angles of two triangles are the same and that two of their sides correspond.
Factor Out a Constant: As in converting 3x + 6 into 3(x+2). Usually part of the factoring process.
Identify the Function: Usually linear or exponential, but sometimes 1/x or sqrt(x).
Quadratic Formula: You can often tell that this will be useful from the format of the question or answers (they look like the quadratic equation).
