For the first 3 years of a horse's life, the weight w (in kilograms) of the horse approximately fits the formula w(t) = 30 + 170
t, where t is the age of the horse in years
which of the following is the most accurate interpretation of the slope of the line represented by this formula
A) the slope is 30. this means that the horse gains a total of 30 kilos in the first 3 years of its life.
B) the slope is 170. this means thst the horse gained on average 170 kilos per year for the first 3 years of its life
C)the slope is 30. this means that the horse gains on average 30 kilos per year for the first 3 years of it's life
D)The slope is 170. this means that the horse gains a total of 170 kilos in the first 3 years of his life

Last Question
Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.
A
=(6*-2) / (5*3) = - 12/15 = -4/5
B
= (7*5) / (4*3) = 35 / 12 = 2 11/12
C
Impossible to do 4/0 cannot be done.
D
= (-2*-4)/(3*5) =
8/15
