What is the slope of a line parallel to the line whose equation is 15x+9y=-16215x+9y=−162. Fully simplify your answer.

-5/3

Step-by-step explanation:

Any line parallel to the given line will have the same slope as the given equation;

Given the equation 15x+9y=-162

Rewrite in standard from y = mx+b

15x+9y=-162

9y = -15x - 162

y = -15/9 x - 162/9

y = -5/3 x - 18

This gives the required equation;

Since mx = -5/3 x

m = -5/3

Hence the slope of the line parallel to the given line is -5/3

it should be a and d. lmk if i'm wrong xd
