Answer:
The Y intercept is -5 and the slope is -5/2
Answer:

Step-by-step explanation:
Given

Required
Find the slope

Subtract 2 from both sides


Open bracket


Take LCM



An equation has the form:

Where

By comparing:
and 

<em>So, the slope is 1/4</em>
Answer:
Option B is correct.
Step-by-step explanation:
We need to find the value of S in cos S = 0.9092
cos S = 0.9092
To find value of S we will find cos^-1(0.9092) i.e
S = cos^-1 (0.9092)
S = 24.6 °
So, the measure of the angle to the nearest tenth of a degree of cos S = 0.9092 is 24.6°
So, Option B is correct.
