Answer:
y=-5x+28 general form
slope point :y-(-7)=-5(x-7)
Step-by-step explanation:
definition :perpendicular slopes are negative reciprocals of each other
x-5y-2=0
y=1/5 x-2/5
slope of the perpendicular line =1/m=-1/(1/5)=-5
slope point :y-(-7)=-5(x-7)
find b :
y=-5x+b
-7=-5(7)+b
b=-7+35=28
y=-5x+28
y=1/5 x-2/5
