Answer:
6n+11=-13
Step-by-step explanation
move all terms to the left:
6n+11-(-13)=0
add all the numbers together, and all the variables
6n+24=0
move all terms containing n to the left, all other terms to the right
6n=-24
n=-24/6
n=-4
n=-4 x=-7
Step-by-step explanation:
the answer is c
Only one of them has a < b in ax² + by² = c formula, making its graph horizontal
All the rest are vertical, see attached
