Answer:

y = -3x + 0.25

Step-by-step explanation:

A line has the following slope-intercept equation:

y = ax + b

In which a is the slope.

Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).

Slope of -3 means that a = -3. So

y = -3x + b

Passes through the point (1.25, -4). Means that when x = 1.25, y = -4

-4 = -3*1.25 + b

b = -3*1.25 + 4

b = 0.25

So

y = -3x + 0.25

Start with the general formula. The key word is difference. So the general formula is 

D(x) = W(x) - R(x) Now substitute in the values for W(x) and R(x)
D(x) = 0.002x^3 - 0.01x^2 - (x^2 - 4x  + 13) Be very careful about the sign in front of the brackets.

D(x) = 0.002x^3 - 0.01x^2 - x^2 + 4x - 13 Do you see what that minus sign did? It affected all 3 terms.

D(x) = 0.002x^3 - 1.01x^2 + 4x - 13 <em>Note: -0.01 - 1x^2 = - 1.01 x^2</em>
That gives you a clear cut answer

C<<<<< answer.

That sign is the worst part of the question. Make sure you understand what it did.
