$\dfrac{1-\cos135^\circ}{\sin135^\circ}=\dfrac{1-\left(\cos^2 67.5^\circ-\sin^2 67.5^\circ\right)}{2\sin67.5^\circ\cos67.5^\circ}=\dfrac{1-\left(1-\sin^2 67.5^\circ-\sin^2 67.5^\circ\right)}{2\sin67.5^\circ\cos67.5^\circ}=\medskip\\=\dfrac{2\sin^2 67.5^\circ}{2\sin67.5^\circ\cos67.5^\circ}=\dfrac{\sin 67.5^\circ}{\cos 67.5^\circ}=\tan 67.5^\circ$

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).

Helga [31]

Answer: $(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

Step-by-step explanation:

Point slope form: $(y-b)=n(x-a)$ , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through $(x_1,y_1)$ and $(x_2,y_2)$ :-

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

So, the equivalent equations are :

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$
