arrange the equations into the form
ax + by = c
1. -14x = -632 - 26y ---> 14x - 26y = 632
slope = 14/26 = 7/13
y = (7/13)x - 316/13 ---> 7x - 13y = 316
slope = -7/-13 = 7/13
since the slopes are equal, they must be parallel.
To be perpendicular, their slopes must be opposite reciprocals of each other.
try the second one.
Can't someone please help me with these equations.
State whether the lines are parallel, perpendicular, or neither.
16. -14x = -632 - 26y
y = (7/13)x - 316/13
18. x + 6y = 196
689 = (6201/230)y + (4823/460)x
I would really apreciate your help.
