Linear Equations and Slopes
A linear equation is an equation with variables to the first power with a constant added to it. The general formula is y = mx + b, known as the slope-intercept form. If an equation has variables to the first power but is not in the form y = mx +b or in the point-slope form, we must first algebraically manipulate the equation to fit one of these two forms...

Complex Numbers
You might have learned this topic from your school classes. However, in SAT or ACT, problems on complex numbers are limited to its addition, subtraction, multiplication, and division. Through this curriculum, you will master the topic of complex numbers in SAT and ACT. Complex Numbers are forms of a + bi, where a and b are real numbers. i^2 = -1, and we call a as the real part, while b is the imaginary part.

Similar Triangles
Triangle similarity deals with triangles that are proportional to each other with respect to angles and sides. There are 3 triangle similarity theorems which include AA(Angle-Angle) theorem, SAS(Side-Angle-Side) theorem, and SSS(Side-Side-Side) theorem. Similar Triangles...
