Question 3 of 15 (1 point) | Question Attempt: 1 of Unlim
The equations of three lines are given below.
1
===x+5
2
Line 1: y=-
Line 2: y=2x-6
Line 3: 2x - 4y= -4
For each pair of lines, determine whether they are parallel, perpendicular, or neither.

Line 1 and Line 3 are neither parallel nor perpendicular. Slopes: -1, 1/2. Product not -1.

Line 1: Equation is in slope-intercept form (y = mx + b), where m is the slope. Thus, for Line 1, the slope (m1) is -1.

Line 2: Equation is in slope-intercept form, so the slope (m2) is 2.

Line 3: We need to rewrite this equation to slope-intercept form. Divide both sides by 2: y = x + 2.

Now, the slope (m3) is 1/2.

Compare Slopes:

Parallel lines: Two lines are parallel if their slopes are equal.

Perpendicular lines: Two lines are perpendicular if the product of their slopes is -1.

Line 1 and Line 2: m1 * m2 = -1 * 2 = -2 (not equal or -1, so not parallel or perpendicular).

Line 1 and Line 3: m1 * m3 = -1 * (1/2) = -1/2 (not equal or -1, so not parallel or perpendicular).

Result: Neither Line 1 nor Line 3 is parallel or perpendicular to each other.

Complete ques:

Determine the nature of the relationship (parallel, perpendicular, or neither) between each pair of lines given their equations:

Line 1: y = −x+5

Line 2: y = 2x−6

Line 3: 2x−4y = −4
