Answer:
y = 3x +8
Step-by-step explanation:
The slope of the given line is -1/3. The slope of a perpendicular line is the opposite of the reciprocal of that: -1/(-1/3) = 3.
Then, in point-slope form, the equation of the line is ...
... y - k = m(x - h) . . . . . for slope m through point (h, k)
... y - 5 = 3(x -(-1)) . . . . . for line of slope 3 through (-1, 5)
... y = 3x +8 . . . . . . . . . simplify
