Write the equation of a line perpendicular to 6x - 5y = - 3 that passes through the pant (- 6, 3). The equation of the line is y = (Simplify your answer Type your answer in slope-intercept form Use integers or fractions for any numbers in the expression.)
Solution
Given that
6x - 5y = -3
First we have to convert this line in slope intercept form y = mx + b for finding slope
- 5y = -3 - 6x
5y = 3 + 6x
5y = 6x + 3
y = (6x + 3)/5
y = (6/5)x + (3/5)
Hence ,
Slope m = 6/5
i.e Slope of first line m1 = 6/5
Perpendicular lines have negative reciprocal slopes.
m1.m2 = -1
(6/5) .m2 = -1
m2 = -1 .(5/6)
m2 = -5/6
Slope of second line m2 = -5/6
y = mx + b
y = (-5/6)x + b
Substitute (-6,3 ) for finding b
3 = (-5/6).(-6) + b
3 = 5 + b
3 - 5 = b
b = -2
Hence ,
The equation of line is ,
y = mx + b
y = (-5/6)x + (-2)
y = (-5/6)x - 2
Therefore ,
The equation of line is , y = (-5/6)x - 2
