Slope-intercept:
y=mx+b

5x-y=9
5x=y+9
y+9=5x
y=5x-9

The answer:   " y = 5x − 9 " .
___________________________________________
Explanation: 
___________________________________________
Given:  " 5x <span>− y = 9 " ; 
___________________________________________
Write  in slope intercept form:
___________________________________________
  " y = mx + b " ;
___________________________________________
         in which "y" is on the left-hand side of the equation, "on its own" (that is, with no "written coefficient")—other than the "implied coefficient of 1 " ;
  "m" is the number, or fraction (positive or negative) representing the slope, if there is one—and "m" is the coefficient of "x"  and "b" is the "y-intercept", if there is one—and may be positive or negative.
_____________________________________________
Given:
__________________
  </span>5x − y = 9 ;
<span> __________________
Multiply the entire equation by "-1" ; to get rid of the "</span>− y " ;
____________________________________________________ <span>
   -1 * {</span>5x − y = 9 } ;
____________________________________________________
   -5x + y = -9 ;

↔  Rewrite as:  y + (-5x) = -9 ;

↔  Rewrite as:  y − 5x  =  -9 ;
___________________________________________
           Add  "5x" to both sides of the equation; to isolation "y" on the left-hand side of the equation:
___________________________________________
             y − 5x + 5x  =  -9 + 5x ; 

to get:    y = -9 + 5x  ;

↔ Rewrite as:  y = 5x + (-9) ;

↔ Rewrite as:  y = 5x − 9 ;
_____________________________
This equation is written is "slope-intercept form"; that is:
___________________________
       " y = mx + b "  ; in which;
                                      m = the slope = 5 ; 
                                      b = the y-intercept =  -9 ;

Number of ponits = number of games won x3 + number of games drawn Grangers have got 42 points. They have drawn 6 games. How many
Helga [31]

Answer:

Number of games Grangers won = 12

Step-by-step explanation:

Given:

Number of ponits = [Number of games won]3 + number of games drawn

Grangers have = 42 points

Number of game drawn = 6 games

Find:

Number of games Grangers won

Computation:

Number of ponits = [Number of games won]3 + number of games drawn

42 = [Number of games won][3] + 6

36 = [Number of games won][3}

[Number of games won] = 12

Number of games Grangers won = 12

Determine the standard form of the equation of the line that passes through (6, -9) and (-8, 6)
horrorfan [7]

9514 1404 393

Answer:

  A.  15x +14y = -36

Step-by-step explanation:

Since we are given two points, we can start with the 2-point form of the equation for a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (6 -(-9))/(-8 -6)(x -6) +(-9)

  y = 15/-14(x -6) -9

Multiplying by -14, we have ...

  -14y = 15x -90 +126

Adding 14y-36 to both sides gives ...

  -36 = 15x +14y . . . . matches choice A

The standard-form equation is ...

  15x +14y = -36

_____

<em>Additional comments</em>

It can be easier to start with the form ...

  (Δy)x -(Δx)y = (Δy)x1 -(Δx)y1 . . . . . where Δx = x2-x1 and Δy = y2-y1

This gives ...

  (6+9)x -(-8-6)y = 15(6) +14(-9)

  15x +14y = -36 . . . simplified

__

You can also start with the slope-intercept form or the point-slope form, if you're more familiar with those. The result will be the same. I find it handy to be familiar with a number of different forms of the equation for a line.
