perpendicular to -5x + y = 5, through (5,5); slope-intercept form

Sagot :

Before finding the perpendicular line, you need to know that perpendicular lines are negative reciprocal of each other. 
x to 1/(-x)
so from the equation thats given:
-5x+y=5 
y=5x+5 set it to slope intercept form
then you will find the slope from the equation which is 5.
Since its perpendicular so the slope of the other line will be 1/-5 or -1/5
then use point slope formula to find the equation of the perpendicular line
y-y1=m(x-x1)     
plug the given coordinate(5,5)
y-(5)=-1/5(x-5)
y-5=-1/5x+1
 +5           +5
y=-1/5+6 will be your answer.!
