The correct answer is C) 1/3 and (0, 1)
The y-intercept part is somewhat simple. In order for it to be a y-intercept, the x value of the ordered pair must be 0. That is only true in B and C, therefore they are the only possible answers. 
To find the slope, we must choose two points on the line and use the slope formula. We can start by using the y-intercept (0, 1) and also (3, 2). Now we use the slope formula. 
m = (y2 - y1)/(x2 - x1)
In this equation m is equal to slope, the first point is (x1, y1) and the second point is (x2, y2)
m = (y2 - y1)/(x2 - x1)
m = (2 - 1)/(3 - 0)
m = 1/3
Now knowing the slope, you can match this with answer C. 
 
        
             
        
        
        
That is impossible to answer because this is an expression. you can only solve for x in equations
        
             
        
        
        
Answer:
The correct response will be "0.01913".
Step-by-step explanation:
According to the question,
p - P(70 years or older) 
= 0.18
n = 4
X = no. of individuals who are older than 70 years
Now,
∴ 
∴
