This document provides a review packet for Algebra 1 with questions on finding equations of lines in slope-intercept form, graphing linear equations, finding x- and y-intercepts, writing equations of lines given slope and a point, solving systems of equations by graphing and substitution, writing equations of parallel and perpendicular lines, and rewriting equations between different forms. There are over 50 short problems covering various topics involving linear equations and systems of linear equations.
Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics
