Answer:
y= -5/3 x - 6
Step-by-step explanation:
3x-5y=20
-5y=20-3x
y= (3/5)x - 5
3/5 is the slope
a perpendicular line's slope is the opposite reciprocal
-5/3 = m
y-y1=m(x-x1)
(-6, 4) = (x1, y1)
plug in the values
y-4= -(5/3) (x+6)
y-4= -5/3 x - 10
1) = 9³
2) = 4*4*4*4*4
= 4 to the fifth power
yes because of a postulate or a theorem
