What is Chapter 4 EQ?
How can you use proportional and non-proportional linear relationships to solve problems? What does it mean to solve a system of equation?
What is a system of linear equations?
A system of linear equations is formed by two or more linear equations that use the same variables.
In y = mx + b, what letter is slope and what letter y-intercept?
m = slope
b = y-intercept
Fill in the blank:

What (7) days did we write down the EQ/Objective/Lesson? (Put in order)
Oct 13th, 16th, 20th, 23rd, 27th, 30th, and Nov 3rd
What is the title of Chapter 4?
Understand Linear Relationships
An ordered pair that makes all the equations in the system true
What is the FIRST step to solving a system of equations by graphing?
Plot the y-intercept of the first slope-intercept form. Then use the slope to plot additional point. Connect points with a line.
