Answer:
The slope of a line parallel to this line will be: -7/9
The slope of the perpendicular line will be:

Step-by-step explanation:
We know the slope-intercept form

Here,
Given the equation

simplifying to write in the lope-intercept form

Thus, the slope of the line is: -7/9
The slope of a line parallel to the line:
We have already determined that the slope of the line is: -7/9
- We know that the parallel lines have the same slope.
Thus, the slope of a line parallel to this line will be: -7/9
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: -7/9
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus,  the slope of the perpendicular line will be:

 
        
             
        
        
        
Answer:
129/2
Step-by-step explanation:
       1                129
64  ---     =       -------
       2                 2
To find the improper fraction, you multiply the denominator by the whole number and then add the numerator.  In the end, you put that answer over the starting denominator.
64 X 2 = 128      128 + 1 = 129     129 / 2 is the answer
 
        
             
        
        
        
let y = x^2
4y^2 -21y + 20 = 0
solve for y
 then substitute back in to get x
