Remark

There are a couple of ways you can do this. The best way is probably the way that avoids dividing by a minus sign. It is a bit longer but division can sometimes cause problems.

Solution

Add gt to both sides.

f + gt = i Subtract f from both sides.

gt = i - f Divide by g

$\boxed{\text{t=}\dfrac{i - f}{g}}$

The point P(5, −4) lies on the curve y = 4/(4 − x).

Answer:

Step-by-step explanation:

Slope refers to the steepness of the line.

Slope is equal to change in value of y divided by change in value of x.

The slope of the secant line is given by $\frac{f(x)-f(a)}{x-a}$ .

Given points are $P\left ( 5,-4 \right )\,,\,Q\left ( x,\frac{4}{4-x} \right )$

So, slope of the secant line is $\frac{\frac{4}{4-x}+4}{x-5}=\frac{4+4(4-x)}{(x-5)(4-x)}=\frac{20-4x}{(x-5)(4-x)}=\frac{-4(x-5)}{(x-5)(4-x)}=\frac{-4}{4-x}=\frac{4}{x-4}$
