Line equation is y = mx+c
y-2 = -3(x-7)
y = -3x+21+2
y = -3x+23 where m = -3; c = 23

y - 2 = - 3x + 21
y = - 3x + 23 (standard form)
Sometimes the equation of a line is put in the form Ax + By + C = 0 in which case:-
3x + y - 23 = 0

those other answers are wrong.
Standard Form is: Ax + By=C
therefore:
y-2=-3(x-7)
y-2=-3x+21
y=-3x+23
-3x+y=23
multiply everything by -1 to make the first term positive and you get:
3x-y= -23

y-2= -3(x-7)
y=-3x+21+2
y= -3x+23 is the standard form

y - 2 = 3 * (x - 7)
y- 2 = 3x - 21
y = 3x - 21 + 2
y = 3x - 19
3x - 19 = -y
3x = 19 -y
x = (19 - y) / 3
