your equation is 3x+y = k , where k is a constant to be found
since it passes through 5,-2, put the value there and find the value of k and place the value of k and you have your equation
the given line in poitn slope form is y = -2x + 7
the slope of the line is m = -2
then using point slope formula where, m = -2 and (5, -2)
y + 2 = -2x +10
2x + y = 8

where did the 2 and 10 come from
Since it's parallel, the new slope would be the same as the new slope, which is -2.
Since you have your new slope and the points (5,-2)
You plug into this linear equation
And Y & X just stays like that.
If you plug in the numbers, you should get.
y = -2x+8
