Answer:
Attached linear graph
Step-by-step explanation:
The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:

and x intercept of:



13x < 18x -24 -6
13x < 18x -30
13x - 18x < -30
-5x < -30
x = 6
The two ratios that are equivalent to, 2:9 are 18:81 and 12:54. Hope it helps
