on a map of uptown Charlotte , College street is perpendicular to Davidson Avenue. The equation y = -6x+8 representing College Street. What is the equation representing Davidson Avenue if it passes through the point ( 7 , -2 ) ?

Question

anonymous · Answer

Can you tell me the slope of y=-6x+8?

anonymous · Answer

its  -6x

anonymous · Answer

Just the number in front of x so -6

so what would the slope be of a line perpendicular to that?

anonymous · Answer

the oppsoite reciprocal :
1/6  (change the sign and flip the fraction)

anonymous · Answer

You then have to use slope-point form o f a line:
y-y1 = m(x-x1)
x1 = 7
y1=-2
