 Lời phê của thầy (cô) giáo
ĐỀ BÀI (đề 1)
Câu1 ( 4đ ): Cho hàm số y = mx + 2
Tìm m để hàm số trên đồng biến?
Tìm m để đồ thị hàm số đi qua A(1; 3)
Với m vừa tìm được vẽ đồ thị hàm số đó.
d) Tính góc tạo bởi đường thẳng vừa vẽ và trục Ox.
Câu 2 ( 2đ ): Cho hàm số bậc nhất y = ax +b. Xác định hàm số biết đồ thị của hàm số cắt trục tung tại điểm có tung độ bằng 2 và song song với đường thẳng y = 2x - 12
Câu 3 ( 4đ ): Cho hai hàm số ( với điều kiện m 1; m ) 
	y = ( m - 1)x + 2k - 3 và y = 3x + k +1
 a) Tìm m, k để đồ thị 2 hàm số trên song song với nhau?
 b) Tìm m, k để đồ thị 2 hàm số trên cắt nhau tại 1 điểm trên trục tung?
 c) Đồ thị 2 hàm số vuông góc với nhau khi nào?
