Step-by-step explanation:
you can simplify the proportion to:

use cross- multiplication
8a = 72
a = 9
9514 1404 393
Answer:
parallel
Step-by-step explanation:
We can put both equations into slope-intercept form to make comparison easier.
-3x = 3 - y ⇒ y = 3x +3
3 +y = 3x -2 ⇒ y = 3x -5
These lines have the same slope, but different y-intercepts.
The lines are parallel.
Answer: slope of the line is 2/3
explanation:
rise over run
go up twice and 3 times to the side
