Answer:


\sf \boxed{\sf D) \ \sf -(5)/(3) }

Step-by-step explanation:


\rightarrow \sf 3x - 5y = -10


\rightarrow \sf - 5y = -10-3x


\rightarrow \sf y = (-10-3x)/(-5)


\rightarrow \sf y= (3)/(5) x+2

Comparing it with slope intercept formula: y = mx + b

  • where m is the slope, b is y intercept

Identify the slope for this function:


\cdot \ \sf slope \ (m) : (3)/(5)

Then perpendicular slope shall be negatively inverse:


\sf perpendicular \ slope = -(m)^(-1) \quad = \quad -((3)/(5) ) ^(-1) \quad = \quad -(5)/(3)
