The slope of the line that passes through points (1,2) and (4,7) is 5/3 or 1 2/3
The cost before increase was $550.
Step-by-step explanation:
Given,
Increased price of plane ticket = $616
Increase percent = 12%
Let,
x be the original price of ticket.
Now,
The original price is 100% and 12% is increased, therefore;
New price = (100+12)% = 112%
Thus;
$616 is 112% of x.
112% of x = 616

Dividing both sides by 1.12

The cost before increase was $550.

1) Since Mia's place is at (5,3) therefore in the I quadrant, and a reflection across the x-axis follows this rule:
Pre-image Image
(x, y) -------------->(x,-y)
(5,3) --------------> (5,-3)
2) So, we can state that Mia is going to have his house in Quadrant II
Hence, the answer is II quadrant
