Answer: the "y=mx+b" form (called the slope-intercept form of the equation of a line). 
Explanation: Finding the equation for a line is a common problem in geometry and trigonometry. There are two common situations where you are asked to find the equation for a line: either you'll be provided with one point on the line and the slope of the line, or you'll be provided two points on the line.
The "b" value (called the y-intercept) is where the line crosses the y-axis.
So point (x1, y1) is actually at (0, b)  
and the equation becomes:
Start with
y − y1 = m(x − x1)
(x1, y1) is actually (0, b):
y − b = m(x − 0)
Which is:
y − b = mx
Put b on other side:
y = mx + b
 
        
             
        
        
        
Some gerontologic changes the nurse should take care of while assessing the older adult patient are c. Decreased gag reflex, d. The increased presence of collagen in alveolar walls, e. Decreased presence of mucus. So our correct options are Options c, d, and e.
- Gerontology is the scientific study of old age, the ageing process, and the unique issues that older people face. 
 - Gerontology's goal is to improve the quality of life by reducing the effects of age-related illnesses and ailments, not prolonging them. The special requirements of older persons, which vary depending on a person's ethnicity, gender, and health, are promoted by gerontologists. 
 - A nursing profession grounded in scientific evidence, gerontological nursing attends to the distinct physiologic, social, psychological, developmental, economic, cultural, spiritual, and advocacy requirements of senior citizens.
