we are given equation of line

$y=\frac{2}{3} x+1$

Equation of perpendicular line:

Firstly , we will find slope of line

$y=\frac{2}{3} x+1$

we can compare it with

y=mx+b

we get

$m=\frac{2}{3}$

we know that

slope of perpendicular line will be -1/m

so, slope is

$\frac{-3}{2}$

It passes through point (-4,5)

so, we can use point slope form of line

$y-5=-\frac{3}{2}(x+4)$

we get

$y=-\frac{3}{2}x-1$ ..........Answer

Equation of parallel line:

Firstly , we will find slope of line

$y=\frac{2}{3} x+1$

we can compare it with

y=mx+b

we get

$m=\frac{2}{3}$

we know that

slope of parallel line always equal

so, slope is

$\frac{2}{3}$

It passes through point (-4,-5)

so, we can use point slope form of line

$y+5=\frac{2}{3}(x+4)$

we get

$y=\frac{2}{3}x-\frac{7}{3}$ ............Answer
