Answer:
√41
Step-by-step explanation:
Top is the formula, and the bottom would be how to plug in the points.
Answer: (-5,4)
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

2005, the price of a TV was $1599.00.
In 2002, the price of the same type of tv has dropped to $399.00
Let’s Calculate the percent of decrease.
First subtract 1599 dollars with 399 dollars to know how much did the price of
TV decreased.
=> 1 599 – 399 = 1 200 is the amount the decreased on TV’s price
=> 1 200 / 1599 = 0.75
=> 0.75 * 100% = 75%
Thus, the price of TV had been decreased to 25%, 75% of it were decreased</span>
y = 8
x = 575
We want to solve for b in the slope-intercept form y = mx + b.
To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:
8 = 575m + b
