Answer:
they are not parallel
Explanation:
Given the equations -3x – 3y = 1 and -3x – 4y = 5
Get the slope of each line
REwrite in the form y = mx+c
For the line -3x-3y = 1
-3y = 3x + 1
y = 3x/-3 + 1/-3
y = -x - 1/3
Slope m = -1
For the line -3x - 4y = 5
-4y = 3x + 5
y = -3/4 x - 5/4
Slope of the line is -3/4
Hence since both lines have different slopes, they are not parallel
