The answers is A x=4.5y because for whatever y is you multiply it by 4.5 and it gives you your x. Trust me. They all match too; I checked.
Answer:
-1
Step-by-step explanation:
Lime m is neither because it does not have the opposite reciprocal nor same slope.
Line n is perpendicular because it has the opposite reciprocal.
Line p is neither because it does not have the opposite reciprocal nor same slope.
Line q is parallel because it has the same slope.
Answer:
B
Step-by-step explanation:
if you look closely, you can see that the side of it goes up 2, then 2, then 1.
Answer:
A.
Step-by-step explanation:
From the given information:
If A = m × n matrix
where;
b is a vector in 
Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.
This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.
Option c and d are equivalent, also option b and c are equivalent.
