Answer:

As the lines are neither parallel nor perpendicular.

Therefore, These lines are neither parallel nor perpendicular.

Explanation:

The slope-intercept form of the line equation


y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the lines

  • y = 3/2x + 2
  • y = 2/3x + 6

y = 3/2x + 2

Finding the slope of y = 3/2x + 2

comparing with the slope-intercept form of the line equation

The slope m₁ = 3/2

y = 2/3x + 6

Finding the slope of y = 2/3x + 6

comparing with the slope-intercept form of the line equation

The slope m₂ = 2/3

So,

m₁ = 3/2

m₂ = 2/3

We know that when two lines are parallel, they have equal slopes

But

m₁ ≠ m₂

3/2 ≠ 2/3

As the m₁ and m₂ are not equal.

Hence, the lines are not parallel.

We know that when two lines are perpendicular, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = 3/2 × 2/3

= 6/6

= 1

As

m₁ × m₂ ≠ -1

Thus, the lines are not perpendicular.

Conclusion:

As the lines are neither parallel nor perpendicular.

Therefore, These lines are neither parallel nor perpendicular.
