Formula Chart for the Heart of Algebra Questions on the SAT® Math Test

A total of 58 Math questions are between you and your dream career. What are you going to do? How can you succeed in the SAT® Math test? First of all, study section by section. The math questions on the SAT® are not divided by math area, but our practice materials are.

A total of 19 out of the 58 Math questions on the actual test will be about the Heart of Algebra. The good news is that you won’t be doing a lot of calculations in these questions, but that means that you have to absolutely dominate handling formulas and mathematical expressions.

To help you with that, we’ve compiled the essential formulas you’ll need to master for the Heart of Algebra questions on the Math Test.

Here are three additional formula charts for the SAT® Math Test:

Category	Formula	Symbols	Comment
Heart of Algebra	\(x+a=b \Rightarrow x=b-a\) \(x-a=b \Rightarrow x=b+a\) \(x \cdot a=b \Rightarrow x=b \div a\) \(x \div a=b \Rightarrow x=b \cdot a\) \(x^a=b \Rightarrow x = \sqrt[a]{b}\) \(\sqrt[a]{x}= b \Rightarrow x= b^a\) \(a^x=b \Rightarrow x=\frac{log\ b}{log\ a}\)	a, b = constants x = variable
Heart of Algebra	\(A \cdot x + B \cdot y = C\)	A, B, C = any real number y = dependent variable x = independent variable	Standard form
Heart of Algebra	\(y = m \cdot x + b\)	y = dependent variable m = slope x = independent variable b = y axis intercept	Slope-intercept form
Heart of Algebra	\(y-y_1 = m(x-x_1)\)	y = dependent variable m = slope x = independent variable b = y axis intercept \((x_1, y_1)\) = given point	Point-slope form
Heart of Algebra	\(m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}\)	m = slope \(y_n\) = independent variable (point n) \(x_n\) = dependent variable (point n)	Slope of a line
Heart of Algebra	\(f(x) = ax^2 + bx + c\)	a, b, c = constants c = y axis intercept x = variable	Standard form
Heart of Algebra	\(f(x) = a(x-h)^2 + k\)	a = constant h = constant (horizontal shift) k = constant (vertical shift) x = variable	Vertex form
Heart of Algebra	\(x= \dfrac{-b \pm \sqrt{b^2-4 \cdot a \cdot c}}{2 \cdot a}\)	a, b, c = constants c = y axis intercept x = variable (x intercept)	Quadratic formula
Heart of Algebra	\(x= \dfrac{-b}{2a}\)	a, b = constants x = axis of symmetry	Axis of symmetry
