Step-by-step explanation:
first of all, let's convert this into a regular line equation :
-x + y = -3
y = x - 3
the x-intercept (the point of the line, where y = 0) is
0 = x - 3
x = 3
so, the point is (3, 0).
the y-intercept (the point of the line, where x = 0) is logically the constant term in the equation : y = -3.
so, the point is (0, -3)
