1) gọi đường thẳng cần tìm là y=ax+b(d1)

vì đt d1 vuông góc vs đt y=2x-1 nên:

a.2=-1 <=> a= \(\dfrac{-1}{2}\)

vì đt d1 đi qua điểm M (-1;1) nên ta có pt:

1=\(\dfrac{-1}{2}\) .(-1)+b <=> b=\(\dfrac{1}{2}\)

Vậy h/s cần tìm là y=\(\dfrac{-1}{2}\) x+\(\dfrac{1}{2}\)

2) gọi đường thẳng cần tìm là y=ax+b(d)

vì đt d // đt y=3x+1 nên:

a=3

vì đt d cắt trục tung tại điểm có tung độ bằng 4 nên : b=4

vậy h/s cần tìm là y=3x+4

3) đk :m\(\ne\)2

vì đt y=2x-1 cắt tại tung độ tại điểm có tung độ bằng -x nên ta có pt :

-x=2x-1 <=> x=\(\dfrac{1}{3}\)

Ta có đt y=mx+1 cắt tại tung độ tại điểm có tung độ bằng -x nên ta có pt :

-\(\dfrac{1}{3}\) =m.\(\dfrac{1}{3}\) +1 <=> m=-4 (tmđk )

Vậy để y=mx+1 va y=2x-1 cắt nhau tại điểm thuộc y=-x thì m= -4

vì hàm số y=(m-1)x+1 là hàm số bậc nhất nên m-1\(\ne\)0 <=>m\(\ne\)1(đk1)

vì d//đt y=-x+1 nên ta có:

-1 = m-1 <=> m= 0(tmđk1)

Vậy m=0 khi d//đt y=-x+1
