By the end of the period, I will graph a linear equation or function in standard form with a
domain { x } and a range { f(x) }.
I will demonstrate this by completing Four-Square Notes and by solving problems in a pair/group activity.

Notes: Standard Form of a Linear Equation
Ax + By = C-Ax -Ax
By = -Ax + C
B B B
y = (-A/B)x + C/B
y = mx + b
A = Coefficient of xB = Coefficient of yC = Constant
Solve for y
