Answer:

Step-by-step explanation:
The point-slope formula is
. When knowing the slope of a line and a point it intersects, we can write its equation with that formula. Substitute
,
, and
for real values.
1) First, find
, or the slope. Use the slope formula
and substitute the x and y values of the given points. Then, solve:

Therefore, the slope of the line is -10.
2) Now, substitute the needed real values into the point-slope formula,
. Since
represents the slope, substitute -10 in its place. Since
and
represent the x and y values of a point the line crosses, choose any of the points given and substitute its values into the formula. (Either one is fine, they both equal the same thing. I chose (2,3).) This will give the following answer and equation:

Answer:
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).
Step-by-step explanation:
this is npt the answer but will help you towards the answer
Check the picture below.
now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².
