Point slope means
y-y1=m(x-x1)
where the slope is m and a point on the graph is (x1,y1)
we are given
slope=-3
therefor
y-y1=-3(x-x1)
eliminate choices A and D
they gave us point (5,-7)
x1=5
y1=-7
y-(-7)=-3(x-5)
y+7=-3(x-5)
C is answer
Answer:
Step-by-step explanation:
Given the length of a fish after t years modeled by the equation
L(t) = 9 − 1/5t
The average rate of growth is expressed as;
dL/dt = -1/5 (differential of a constant is zero)
Hence the average rate of growth over the first year of life is -1/5 in/year
10*8000= 80,000
An easy way to multiply by 10 is to shift the decimal place over by 1 place value and add a 0 right before it.
