Find the angle made by the line joining 5,3 and -1,-3 with the positive direction of x-axis

45°

Step-by-step explanation:

gradient of the line:

Let A (-1,-3) and B (5,3)

tan a = (yB - yA) / (xB - xA) = (3 - -3) / (5 - -1) = 6/6 = 1

--> the angle made by the line and positive direction of x-axis is:

The simplest form of a fraction occurs when the numerator and denominator cannot get any smaller (while still being integers)

In the stadium there are 30 suites.

14 suites24 seats
16 suites18 seats

The suites with 24 seats are 14 out of 30 which can be represented as 14/30.

However, the simplest fraction would be 

  7*2        7
=  
 15*2      15
