1) Parallel lines have the same slope, so the answer is 1/2
2) Perpendicular lines have slopes that are negative reciprocals, so the answer is -2
3) The equation of the perpendicular is y = -2x - 6, so a point is (0, -6)

361 congruent square tiles would be needed to cover the square shaped floor.
<h3>Equation</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.
Counting one tile twice, there are:
- 37=2x-1
- x=19 tiles on each side.
19² = 361
361 congruent square tiles would be needed to cover the square shaped floor.

It would be: 360- (101+133+76)
360-310 = 50 degree
