Given points and determine the pairs of lines are perpendicular: b) 3y = x+3 and y+3x=1, d) y+4x=2 and y−4x=1, f) y=5x+3 and y=-5x+1. 3 on the same Cartesian plane. -2). Another line L2 passes through perpendicular to L2, draw the two lines at the point of intersection.

Badilisha $3y = x + 3$ kuwa umbo la $y = mx + c$.

Mteremko wa mstari wa kwanza ni $m_1 = \frac{1}{3}$.

Badilisha $y + 3x = 1$ kuwa umbo la $y = mx + c$.

Mteremko wa mstari wa pili ni $m_2 = -3$.

Kwa kuwa bidhaa ya miteremko ni $-1$, mistari hii ni wima.
$\boxed{\text{Mistari ni wima}}$

Badilisha $y + 4x = 2$ kuwa umbo la $y = mx + c$.

Mteremko wa mstari wa kwanza ni $m_1 = -4$.

Badilisha $y - 4x = 1$ kuwa umbo la $y = mx + c$.

Mteremko wa mstari wa pili ni $m_2 = 4$.

Kwa kuwa bidhaa ya miteremko si $-1$, mistari hii si wima.
$\boxed{\text{Mistari si wima}}$

Mstari wa kwanza tayari uko katika umbo la $y = mx + c$.

Mteremko wa mstari wa kwanza ni $m_1 = 5$.

Mstari wa pili tayari uko katika umbo la $y = mx + c$.

Mteremko wa mstari wa pili ni $m_2 = -5$.

Kwa kuwa bidhaa ya miteremko si $-1$, mistari hii si wima.
$\boxed{\text{Mistari si wima}}$
