Answer:
y = -3x - 2
Step-by-step explanation:
y=The given line is y = (1/3)x-3. The slope of a line perpendicular to this one is the negative reciprocal of (1/3), which is -3.
Use the point-slope form of the equation of a straight line, taking the given point (h,k) to be (-3,7):
y - k = m(x - h). Fill in the given info:
y - 7 = -3(x + 3), or y = -3x - 9 + 7.
Simplifying, we get y = -3x - 2.
