A good way to memorize formulas is to memorize that as both text and image. Convert the formula into text, memorize the text by saying it out loud to yourself and copying it out as a mathematical formula. Before you take the SAT, drill yourself on the formulas and concepts.

What are some things you need to memorize for the SAT math?

**The Slope Formula**

If you have the coordinates of two points, to calculate the slope of a line, use the following formula:

“Y two minus Y one over X two minus X one.”

** ****The Distance Formula**

“Distance is the square root of Y two minus Y one squared plus X two minus X one squared.”

Distance is exactly the same as the Pythagorean theorem, where the distance between two points is the hypotenuse of a right triangle.

**The Midpoint Formula**

If you have coordinated for two points, calculate the midpoint by averaging the x coordinated and averaging the y coordinates.

**The Quadratic Formula**

The quadratic formula can be used to find the X-intercepts of a parabola:

“Negative b plus or minus the square root of b squared minus 4ac all over 2a.”

**How to get the X-coordinate of the vertex of a parabola in standard form:**

“Negative B over 2A”

If you need the Y-coordinate of the vertex, plug the X-coordinate you got into the equation.
