Answer:

B

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to \frac{3}{2}

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (r, - 4)

m = \frac{-4-2}{r-3} = \frac{-6}{r-3} , then equating gives

\frac{-6}{r-3} = \frac{3}{2} ( cross- multiply )

3(r - 3) = - 12 ( divide both sides by 3 )

r - 3 = - 4 ( add 3 to both sides )

r = - 1 → B

You have to find LCD (lowest common denominator) in this case it will be 5x:

\frac{u}{x}+\frac{5u}{x}- \frac{u}{5x}=\frac{5*u}{5x}+\frac{5*5u}{5*x}- \frac{u}{5x}=\frac{5u+25u-u}{5x}=\frac{29u}{5x}
