y=1/3x+5y=13x+5

Explanation:

Given -

2y=-6x+82y=6x+8

y=(-6)/2 x+8/2y=62x+82
y=-3x+4y=3x+4

The slope of this line is m_1=-3m1=3

Another line is passing through (0, 5)(0,5)
This line is perpendicular to the line y=-3x+4y=3x+4

Find the slope of the other line -

m_2m2 is the slope of the other line.

For two lines to be perpendicular -

m_1 xx m_2 = -1m1×m2=1

Then

m_2=(-1)/(-3)=1/3m2=13=13

The equation is

y=mx+cy=mx+c
y=1/3x+5y=13x+5
