Question

What is the slope of a line parallel to the line whose equation is 9x-3y=-54

Answer 1

21

Explanation:

subtract 9 on both sides to make your x axis by itself

y=mx+b

since -3y and -63 will cancel out each other and make a positive when you divide

-3y /63

y=21

also your when the x is alone it is always 1

rise

-------

run

Answer 2

9x = 3y - 54
3y = 9x + 54
y = 3x + 18
Parallel = same slope
The slope is 3
