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}

RSB [31]

Answer:

\boxed{\dfrac{1}{2} = m}

Step-by-step explanation:

Given equation:

\dfrac{3}{4} = m + \dfrac{1}{4}

<u>Step-1: Subtract 1/4 both sides</u>

\dfrac{3}{4} = m + \dfrac{1}{4}

\dfrac{3}{4} - \dfrac{1}{4} = m

\dfrac{2}{4}  = \boxed{\dfrac{1}{2} = m}
