Bell ringer
Use graphing calculator to solve linear equations:
A) - y = - y
B) 4 (x – 2)= 4x
Objective
Students will use graphing calculator to solve system of equations with 90% accuracy.
“WE CAN” determine the number of solutions to a pair of equations
to graph a constant (number only) enter y=??y=c
“WE CAN” solve pairs of linear equations using the GDC
Bell ringer
Use GDC to solve systems of equations
(A)2y = -4x + 2 2y = x-16
(B) 2y = -6x +2 -4 = y + 3x

Word problem
Your family is planning 7 days trip. You estimate it will cost $275 per day in Tampa and $400 per day in Orlando.Your total budget for 7 days is $2300. How many days should you stay in each city?
“WE CAN” solve pairs of linear equations using the GDC
Objective
Students will solve quadratic equations using graphing calculator.
“WE CAN” solve quadratic equations using the GDC.
Factoring
2x
4x² - 8x + 16= 4( ? – 2x + ?)
5x² + 25 = ? ( ? + 5)
2x²- 10x = 2x( ? - ?)
