(-3,1) which is perpendicular to line 7y-5x-7=0
.
7y-5x-7=0
7y=5x+7
/7
y= 5x/7 +1
slope = 5/7
...
The slope of line perpendicular to this line will be -7/5
point ( -3,1)
Plug value of a,y & m to get value of b
in y= mx+b
1=-7/5 * -3 +b
1=21/5 +b
1-21/5 = b
-16/5 =b
The equation will be
y= -7/5 x -16/5

Calculate the slope of the given line, take the opposite of the coefficient on divided by the coefficient on

Calculate the slope of the desired line by taking the negative reciprocal of the given line. Because:



Use the point-slope form of an equation of a line:



where are the coordinates of the given point and is the calculated slope.
