The correct answer is: [A]: " x(y – 5) = 2 " .
_____________________________________________________
Consider:
_____________________________________________________
Choice: [A]: " x(y–5) = 2 " ;

Divide each side by "x" ;

" [x(y – 5)] / x = 2/x " ;

→ y – 5 = 2/x ;

Add "5" to each side of the equation:

y – 5 + 5 = 2/x + 5 ;

→ y = 2/x + 5 ; not a line; since one cannot divide by "zero" ; there would be no "point" on the graph at "x = 0". So, this answer choice: [A] is correct.
_______________________________________________________
Choice [B]:

y -2x -18 = 0

y - 2x = 18

y = 18 + 2x ; y = 2x + 18 ; is a line.
_________________________________________________
Choice C) 3y + 12 - 6x = 5 ;

3y = 5 - 12 + 6x ;

3y = -7 + 6x ; 3y = 6x - 7 ; y = 6x/3 - 7/3 ; y = 2x - 7/3 ; is a line.
_________________________________________________
Choice: [D]:

2(y+x) = 0 ;

[2*(y+x)] / 2 = 0/2 ; y + x = 0 ; y = -x ; is a line.

Shannon drew the line of best fit on the scatter plot shown below:

N76 [4]

Using the points (0,14) and (10,0), the gradient of the line is (14-0)/(0-5) which simplifies to -7/5.

From these points, we can also see that when the x value is zero, the y value is 14. Therefore the y-intercept is 14.

We can then put this into the equation of a straight line, y=mx+c:

y = (-7/5)x + 14
