Solving by Substitution - 22:48

This video looks at solving by substitution and find the point of intersection of a linear system without graphing. We will see what to look for when solving by substitution to see whether there is one solution, no solution or...

Solving by Graphing - 14:43

This video looks at solving linear systems by graphing. We recall how to graph linear systems using the slope intercept form of y=mx+b. We look at how to graph and how to identify the point of intersection of a linear...

Introduction to Linear Systems - 7:18

In this video, I introduce the 3 possible outcomes when solving linear systems. Linear systems are a set of 2 or more lines and it is up to us to determine where these lines will intersect one another, IF they...

Tricky Slopes and y-Intercepts - 14:34

KEY CONCEPTS: In order to use the slope and intercept rules, equation MUST be in the form of y=mx+b TRICKS to be Careful of: y=4 (horizontal line - therefore slope is 0) x=4 (vertical line - therefore slope is undefined)

Slope y-Intercept Form - 20:48

KEY CONCEPTS: Slope/y-Intercept form is: y=mx+b m=slope (value in front of x ONLY when in this form y=mx+b) b=y-intercept slope=rise/run
