Đồ thị hàm số y=ax đi qua điểm M(-3;5)

a) Hãy xác định a

y=ax => 5=a(-3)

=> a=5:(-3)

=> a=\(\dfrac{-5}{3}\)

b) Tìm trên đồ thị hàm số điểm Q có tung độ bằng 2 và điểm P có hoành độ bằng 6

+Xác định điểm Q: y=ax=> 2=\(\dfrac{-5}{3}\)x

=> x= 2:\(\dfrac{-5}{3}\)= \(\dfrac{-6}{5}\)

Vậy ta có: Q(\(\dfrac{-6}{5}\);\(\dfrac{-5}{3}\))

+Xác định điểm P: y=ax=> y=\(\dfrac{-5}{3}\).6= (-10)

Vậy ta có: P(6; -10)
