about straight lines (20point)

5該可5可以幫我解解下面D問題(20 point !!!!!)
我要埋step，5係 only answer

1)Find the equation of the straight line passing thought the point(-8,7) and parallel to the Y-axis.

2)Find the equation of the straight line passing thought the point(-3.3,-5.6) and parallel to the x-axis.

In each of the following, find the equation of the line which passes thoght the point with the given coordinates and has the given slope m.
3)(1.2),m=1/2 ||| 4)(-2,-1),m=3/2 ||| 5)(0,1/2),m=1/3 ||| 6)(1/2,1/3),m= -5/4

In each of the following, find the equation of the straight line which passes thought the given pair of points.
7)(-3,1),(-1,-1) ||| 8)(-1,-4),(-2,-5) ||| 9)(1,1/5),(2/3,-2)

In each of the following, find the value of the unknown k for the straight line L.
10)L: x-y+3=0 with slope k ||| 11)L: 2x-y+k=0 with y-intercept |||
12)L: y-kx-1/2=0 with slope -1/3 ||| 14)L: y+5x+8=0 with y-intercept k
