#5: DAY 8
MTH 110 – 10 & 17
W11
DAY 8
: Wednesday 2/2 and Thursday 2/3,
whole class
OBJECTIVES:
1.
Understand the nature of a system of linear equations in 2 variables (x & y),
and the goal for SOLVING a system is to find the (x, y) which satisfies or is a SOLUTION for
BOTH equations of the system.
2. Review the 3 methods for solving a linear system of
equations ( graphing, elimination & substitution) and master/apply
at least one method to a
given system.
3. Be aware of 3 possibilities for a system’s solution form: one solution (x,y)
(lines intersect), NO solution (lines are parallel) or INFINITE solutions (lines coincident (same
line)), and how to distinguish such systems within each method.
4. Begin look at linear system
applications, solving systems with 2 unknowns and 2 known relationships.
SCHEMA ACTIVATION:
Recall the internet usage and cost handout of 2 plans and methods
of solution for finding when the two plans A & B were equal in cost.
