SAT Prep: Test 3 Section 4 Part 5
The last part of problem 18 is the focus of this short video. Sal picks up where he left off, factoring the end of the linear equation, and reminding students to view his video on factoring if they are still confused.
Khan Academy
Graphing Using X and Y Intercepts, Graphing Lines and Slope, Algebra Basics
After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.
Khan Academy
Consistent and Inconsistent Systems, Algebra II
First, Sal defines consistent and inconsistent equations. He then evaluates a system of linear equations to determine if they are consistent or not. This resource isobviousr and would be a wonderful video to show before a test or at an...
Khan Academy
SAT Prep: Test 2 Section 3 Part 3
Covering geometry, linear equations, and mathematical patterns, Sal discusses problems 9-12 on the practice SAT. His easygoing manner and clever calculations will keep students' interest far longer than reviewing SAT questions from a...
Khan Academy
SAT Prep: Test 3 Section 8 Part 3
Geometry and algebra are equally represented in this video, which covers problems 10-14 on the practice SAT. As always, Sal is the expert of quick, efficient ways to solve problems - especially helpful for students who have a difficulty...
Khan Academy
Graphical Systems Application Problem, Systems of equations
Sal evaluates a word problem and then solves it by graphing systems of equations. This problem would be significant as a daily challenge, as a concept review, or as a homework assignment. Show this video only after the students have had...
