Answer:

y = -9x - 19

Explanation:

y + 9x = -2 ==> convert this equation into slope-intercept form

y + 9x - 9x = -9x - 2

y = -9x - 2 ==> equation is now in slope intercept form

Parallel lines have same slope:

The line parallel to 'y = -9x - 2' has a slope of -9

y = -9x+b

-10 = -9(-1)+b ==> substitute all known variables

-10 = 9 + b

-10 - 9 = 9 - 9 + b

b = -19

y = -9x+ (-19)

y = -9x - 19
