Answer:
y = 2x - 3
Yes, your answer is correct.
Step-by-step explanation:
First, find the slope of the two points by using the slope formula:
         y2 - y1
m = ------------- 
         x2 - x1
          13 - 5
m = ------------- 
           8 - 4
          8
m = ------- = 2
          4
To find the y-intercept, plug in values into the slope-intercept formula:
y = mx + b
Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):
5 = (2) (4) + b
5 = 8 + b
-3 = b
b = -3
So, putting everything into the slope intercept formula:
y = 2x - 3

Answer:
because you can't get closer to 0 on the number line than 0 units away.
Step-by-step explanation:
it's like walking if the point is 3 foot in front of you and you walk to it once you get to it then even if you keep walking you can't go a negative number of feet away from it because the closest you can get is right on it.
 
        
             
        
        
        
Solution :
Given : 
National mean score of the reading test that is conducted the NAEP = 288
Standard deviation of the score = 38
Therefore, P(X > x) = 0.25
P (Z >  = 0.674)
 = 0.674)


x = 326.67
Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.
 
        
             
        
        
        
Answer:
The first one: {{7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
Functions can't have repeating x values. Each x has to have its own y value.
