Line A has a slope of -2/3 and passes through (-4,-1). Line B passes through (-4,5) and (-1,3). Are these lines Parallel, perpendicular, or neither?
I will mark branliest too!!!

Respuesta :

The given lines are parallel i.e. Line A || Line B

Further explanation:

Slope of line A = m1 = -2/3

We have to find the slope of second line

Let m2 be the slope of line B

[tex]m_2 = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here,

(x1,y1) = (-4,5)

(x2,y2) = (-1,3)

[tex]m_2 = \frac{3-5}{-1-(-4)}\\m_2 =\frac{-2}{-1+4}\\ m_2 = -\frac{2}{3}[/tex]

We can see that:

[tex]m_1 = m_2[/tex]

The slopes of parallel lines are equal. Hence the given lines are parallel i.e. Line A || Line B
