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
Another line is passing through
This line is perpendicular to the line
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=−1−3=13
The equation is
y=mx+cy=mx+c
y=1/3x+5y=13x+5
