svet-max [94.6K]

Answer:

$m=\frac{1}{2}$

Step-by-step explanation:

defition of slope(m) of a line:

$m=\frac{Y_b-Y_a}{X_b-X_a}$

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5

B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

$m=\frac{-3-(-5)}{3-(-1)} \\\\m=\frac{-3+5}{3+1} \\\\m=\frac{2}{4} \\\\m=\frac{1}{2}$

Answer:

$\dfrac{z-y}{a+b}$

Step-by-step explanation:

Given expression:

$\dfrac{z^2-y^2}{a^2-b^2}\div \dfrac{z+y}{a-b}$

Substitute

$a^2-b^2=(a-b)(a+b)\\ \\z^2-y^2=(z-y)(z+y)$

into the expression:

$\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\div \dfrac{z+y}{a-b}\\ \\ \\=\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\times \dfrac{a-b}{z+y}\\ \\ \\=\dfrac{z-y}{a+b}$
