Question

Please answer this! I could not figure it out. Neither could my classmates.

Answer 1

D

Step-by-step explanation: i got it right

Answer 2

`\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)`
