Let's start working with equation A:
y = 3x - 2
Slope intercept form:
y = 3x - 2
Slope
m = 3
Equation B:
3x + y = 5
Slope intercept form:
y = -3x + 5
Slope
m = -3
Now, let's graph the slope intercept form of both equations, as follows:
As we can confirm, A and B, are neither parallel nor perpendicular
