Step-by-step explanation:
15. Not enough Information. I need to know how many pencils she had in all
Here, equation of a line, y + 2 = 1/3 (x -5)
slope = 1/3
Slope of the line which is perpendicular would be -3 [ reciprocal & opposite ]
Now, y - y1 = m(x-x1)
y - 3 = -3(x - (-4))
y - 3 = -3x - 12
y = -3x - 9
In short, Your Answer would be y = -3x - 9
Hope this helps!
