IF IT IS THE EQUATION OF A LINE YOU ARE LOOKING FOR:
y=mx+c
7-1÷5-3=6÷2=3
y=3x+c (here we substitute in one of the points to find out what C is)
1=(3×3)+c
1=9+c
-8=c
so the equation is: y=3x-8

Answer:
x = 45
Step-by-step explanation:
AB // CD,
∠AB0 + ∠COB = 180 {Co interior angles}
75 + ∠COB = 180
∠COB = 180 - 75 = 105
∠DOE =∠COB {Vertically opposite angles}
∠DOE = 105
In ΔDOE,
x + 30 + 105 = 180 {angle sum property of triangle}
x + 135 = 180
x = 180 - 135
x = 45
