Answer:
y+x = 5
Step-by-step explanation:
Given the equation y = x + 14
Get the slope first
The slope m = 1
Since the required equation is perpendicular to the line, the required slope will be M = -1/1 = -1
Get the required equation using the equation y-y0 = m(x-x0)
(x0, y0) = (-3, 8)
y - 8 = -1(x-(-3))
y-8 = -(x+3)
y-8 = -x-3
y+x = -3+8
y+x = 5
Hence the required equation of the line is y+x = 5
