6y-x =12
6y=x+12
y= (1/6)x +12
slope = 1/2
Slope of perpendicular line will be negative reciprocal of (1/6)
slope = -6
This line with slope -6 passes through -1 ,2
plug these values to get value of b
y=mx+b
2= -6*-1 +b
2+6=b
b=-4
The required equation is y = -6x -4
Solve the given equation for in terms of . The coefficient on will then be the slope of the graph of that equation.
Perpendicular lines have negative reciprocal slopes. Find the negative reciprocal of the slope of the given line which will be the slope of the desired line.
Once you have the slope of the desired line, use the Point-Slope form of an equation of a line to derive the desired equation.
