If you divide 64 by 4 then u get 16 so r is 16
OK. So first, slope = rise/run. This can be calculated with any 2 points from the graph above.
I will use points (24, 168) and (8, 56).
Slope = (168 - 56) / (24 - 8)
Slope = 7
Since the y-intercept is 0, the equation is y = 7x
B should be the correct answer.
Cheers,

Answer:
Step-by-step explanation:
First, open the brackets.
(2x + 4) + (-7 - 3b) + (5 - 8x)
= 2x + 4 -7 - 3b + 5 -8x
Simplify the like terms.
= 2x - 8x - 3b + 4 -7 + 5
= -6x - 3b + 2
<span>The slope is the differential of the function.
Recall, if y = x^n, (dy/dx) = nx^(n-1).
y=</span><span>x^4-20x^2+64; x = -1. To differentiate this, we do it for each term.
(dy/dx) = (4)(x^(4 -1)) - (2)(20x^(2-1) + 0*64x^(0-1) (Note 64 = 64x^0, x^0 =1)
= (4)x^(3) - 40x^(1) </span><span><span>+ 0
= 4x^3 - 40x^1.
</span>(dy/dx) = </span><span><span><span> 4x^3 - 40x</span>. Note at x = -1.
</span>
(dy/dx), x = -1, = 4(-1)^3 - 40(-1)
<span> = -4 + 40 = 40 - 4 = 36.
</span><span>
Slope at x = -1 is 36.

Oki! I'll help!
The answer is:

<em>Here is the whole work I did, so you can understand how to get the answer!</em>
<em>1. Divide 374 by 7</em>
374 ÷ 7 = 53.4
<em>2. Round to nearest whole number</em>
Since 4 in the tenth place is closer to zero than one, we round it down and get 53.
Oh the thing surrounding the whole work I did is just a spacer to make the answer not boring!
