ANSWER
Yes it is very true
<u>EXPLANATION</u>
If the two equations intersect at 
then this point must satisfy the two equations.
We substitute in to erquation (1)
We now substitute in to erquation (2) also
Since the point satisfy all the two equations, it is true that they intersect at

Answer:
Restudy and try to take it again.
Step-by-step explanation:
Try watching math videos and do extra studying on the areas you missed on your last attempt.
None But, 80 x 2 = 160 and 80 + 2 = 82, are you sure you mean 92?
