I don't know if this is the right place, but I'll post it anyway :)

<p>If b > 1, what is the slope of the line in the xy-plane the passes through the points ( b, b^2) and (b^2, b^4)?</p>

<p>(A) -b^2 + 5b</p>

<p>(B) -b^2 + b</p>

<p>(C) -b^2 - b</p>

<p>(D) b^2 - b</p>

<p>(E) b^2 + b</p>

2

<p>E. Plug in the coordinates into the formula (y2-y1)/(x2-x1) and simplify.</p>

3

<p>I did so, but look at “B”, it gives the same exact answer of “E”</p>

4

<p>A simple way would be to take the value of B. Since B>1 then let B equal to 2.</p>

<p>You get the co-ordinates as (2,4) and (4,16). You’ll get the line and calculate it in terms of 2. Then replace B by 2. You’ll get your answer.</p>
