Identify which lines are parallel.
y=2;y=x+2;y=2x-1;y=2x+1

y=2

Step-by-step explanation:

A parallel line are lines that never intersect.

-They are generally formed when a line when lines are perfectly horizontal to the x axis or the vertical to the y-axis.

=>y=2 is the only parallel line .

=>y=x+2 is not parallel as the (x+2) is not a constant

=>y=2x-1 is not parallel as the (2x-1) is not a constant

=>y=2x+1 is not parallel as the (2x+1) is not a constant

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
