First, we find the equation of the line...
(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1
y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
 y = -x + 4
Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x
y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)
        
             
        
        
        
It is customary to work left to right, however that is not a rule.  In order of operations, the actual rule is that multiplication/division occurs after parentheses, exponents, and before addition/subtraction...
PEMDAS  order of operations
Parentheses, exponents, mutiplication/division, addition/subtraction.
        
             
        
        
        
The general rule for the nth term of the sequence is 
Explanation: 
The sequence is -6b, -3b, 0b, 3b, 6b, .....
To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.
First term of the sequence = -6b
Common difference = 
Using this the nth term of the sequence can be determined.
Since, this is an arithmetic sequence, the general form of AP is given by the formula,

where a denotes the first term of the sequence and d denotes the common difference. Thus,  and
 and 
Substituting the values in the general formula, we get,

Thus, the general rule for the nth term of the sequence is
