Anything raised to exponent 0 equals 1
So

So we get

Answer:
y= -1/5x + 1/5
Step-by-step explanation:
y- y1 = m(x - x1)
Slope m=-1/5
(1, -4)
1 = y1
-4 = x1
y- 1 = -1/5(x-(-4))
y-1 = -1/5(x+4)
y-1= -1/5(x)+ -1/5(4)
y-1 = -1/5x + -4/5
add one to both sides
y= -1/5x + -4/5 + 1
y = -1/5x + 1/5
No it doesn't become positive
In order to know that, you need to divide 7 from 4730
It would be: 4730/7 = 675.71
So, your final answer is 675.71
Hope this helps!
