March 31: Substitution Method II
Today we will discuss using the substitution method to solve systems of equations when one of the equations is in standard form and the other is in slope intercept form. Pleas watch the first video and complete 16-20 on pg 6 (it is located above in yesterday's work as 4.2 substitution) the answers are on pg 8.
There is a second video today from some work submitted by one of your classmates. It reviews solving systems of equations by graphing and a common mistake that people make when solving.
