Question

The equations of four lines are given. Identify which lines are parallel. Line 1 y=-3/4x-8

Line 2 y+3=-1/8(x+6)
Line 3 y=-8x -4
Line 4 x+4/3y=6

Answer 1

Line 1 and line 4.

Explanation:

if to re-write the equation of the Line 4, then y= -3/4x+8;

the lines are parallel if their coefficients of x are the same value. It means, for line the slope is -3/4, for line 4 the slope is -3/4; finally they are parallel.
