B is the Y-intercept or where the graph crosses the y-axis. they provide you with a few things which can help you figure this out. they give you the values of x and y in a table
X | Y
2  |  -5
4  |  -9            The difference between each Y value is 4...so, I add 4 to the -5
6  |  -13            and get -1...going up another value for the X would be at 0.  This leaves me with an ordered pair of (0,-1).....thus, the value of b is -1.
        
             
        
        
        
N, O, S, and Z all have rotational symmetry
        
                    
             
        
        
        
Answer:
x = 3 and y = 5
Step-by-step explanation:
Given equations are :
y=5x−10 ..(1)
y=−3x+14 ...(2)
Subtract equation (2) from (1).
y-y = 5x−10-(−3x+14)
0 = 5x-10+3x-14
0= 8x-24
8x = 24
x = 3
Put the value of x in equation (1).
y=5(3)−10
= 15-10
y = 5
So, the values of x and y are 3 and 5 respectively.
 
        
             
        
        
        
Answer:
wut thut u better tell me -_-
Step-by-step explanation:
 
        
                    
             
        
        
        
Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price. 
60% of x = 2.8
Simply means: 60/100 * x = 2.8
You solve for x, which comes out to $4, which is your original price.
