Give you supplementary knowledge first! Two straight lines are parallel and have equal slopes. That is a 1b2 = a2b 1. A 1c2 is not equal to A2C 1, so A=3 C is not equal to -2.

The intersection is not parallel, so a is not equal to 3 and c is equal to R.

The vertical slope is multiplied by-1a1B2+a2b1= 0a =-4/3c = r.

The second question is the same as above, and the answer m is not equal to 3 or -6.

M=3 or -6

m=-3/8

The intersection of the third question (-2,2) k1= 3/2 vertical K2=-2/3 so the straight line Y-2=-2/3(x+2).

The intersection (3,2) is parallel to K 1=4/3 K2=4/3, so Y-3=4/3(X-2).
