Determine if the given lines are parallel, perpendicular, or neither.
Leni [432]

Answer:

The lines are parallel.

Step-by-step explanation:

Given the lines

-2x-3y=9

4x+6y=24

Writing the equations in the slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept

-2x-3y=9

y=-\frac{2}{3}x-3

Thus, the slope = m₁ = -2/3

also

4x+6y=24

  • y=-\frac{2}{3}x+4

Thus, the slope = m₂ = -2/3

  • We know that parallel lines have equal slopes

As

m₁ = m₂

Thus, the lines are parallel.
