Algebra I Formula Sheet Below are the formulas you may 􀀝nd useful as you take the test. However, you may 􀀝nd that you do not need to use all of the formulas. You may refer to this formula sheet as often as needed. | Linear Formulas Slope Formula
m = y2}x2––yx11
Linear Equations
Slope-intercept Form: y = mx + b
Point-slope Form: y – y 1 = m(x – x1)
Standard Form: Ax + By = C
Arithmetic Sequence Formulas
Recursive: an = an – 1 + d
Explicit: an = a 1 + d(n – 1)
Exponential Formulas
Exponential Equation
y = ab x
Geometric Sequence Formulas
Recursive: an = r(an – 1) Explicit: an = a 1 • rn – 1
Compound Interest Formula
A = P( 1 + r}n)nt
Quadratic Formulas
Quadratic Equations
Standard Form: y = ax2 + bx + c
Vertex Form: y = a(x – h)2 + k
Quadratic Formula
x = 2}a– 4ac
_______ | Average Rate of Change
The change in the y-value divided by the change in the x-value for two distinct points on a graph.
Statistics Formulas Mean
= x}1 + x2 + xn
Interquartile Range
IQR = Q3 – Q1
The difference between the 􀀝rst quartile and third quartile of a set of data.
Mean Absolute Deviation

The sum of the distances between each data value and the mean, divided by the number of data values. | | --- | --- | You can find mathematics formula sheets on the Georgia Milestones webpage at [http://www](http://www) .gadoe . org/Curriculum-Instruction-and-Assessment/Assessment/Pages/ Georgia-Milestones-EOC-Resources . aspx .

Item 1 Selected-Response Sandra makes necklaces and sells them at a school craft fair . She uses the equation P = 7 .5n –(2 .25n + 15) to determine her total profit at the fair when n necklaces are sold . Based on this equation, how much does she charge for each necklace? A . $2 .25 B . $7 .50 C . $15 .00 D . $17 .25 Item 2 Selected-Response The perimeter of a rectangle is P = 2w + 2l, where w is the width of the rectangle and l is the length of the rectangle . Rearrange this formula to find the width of the rectangle . A . w = P – 2l P B . w = _____ 4 – l C . w = 2P – l P D . w = __2 – l Georgia Milestones Algebra I EOC Study/Resource Guide for Students and Parents Page 223 of 272 Copyright © 2019 by Georgia Department of Education.

The Mascot Company wants to spend no more than 1,250 dollars per month on the cost of school spirit items for sporting events . Production costs are 5 dollars per shirt and 8 dollars per banner . The company also wants monthly gross revenue from selling shirts and banners to be greater than 3,000 dollars . One shirt sells for 15 dollars, and one banner sells for 20 dollars . An employee at the company wants to determine the number of shirts and banners that Mascot Company should produce for a month . He lets s represent the number of shirts and b represent the number of banners . He writes the following system of inequalities . 5 5s + 8b ≥ 1,250 15s + 20b > 3,000 Part A Explain why the inequality 5s + 8b ≥ 1,250 incorrectly models the company’s monthly production costs . Write your answer in the space provided . Part B Explain why the inequality 15s + 20b > 3,000 correctly models the company’s monthly gross revenue . Write your answer in the space provided .

FAQs

What linear equation forms are included on the formula sheet?

The sheet lists slope-intercept form (y = mx + b), point-slope form (y − y1 = m(x − x1)), and standard form (Ax + By = C).

Which quadratic forms and formula are provided?

It provides the standard form (y = ax^2 + bx + c), vertex form (y = a(x − h)^2 + k), and the quadratic formula (x = (−b ± √(b^2 − 4ac))/2a).

What types of EOC practice items appear in the guide?

The guide includes selected-response questions, constructed-response prompts, and technology-enhanced activities such as drag-and-drop and multi-select ordered-pair/function tasks.
