Answer:
Step-by-step explanation:
y = x + 9 is the given equation of a line. The coefficient of 'x' is 1. Therefore the slope of this line is 1.
The slope of any line perpendicular to this y = x + 9 is the negative reciprocal of 1, which is -1.
Using the point-slope formula for the equation of a straight line, y - k = m(x - h), we identify h and k as -2 and -2 respectively, from the given point (-2, -2).
Then, y - k = m(x - h) becomes y + 2 = -1(x + 2) (in point-slope format)
