First, find the slope of the line that is perpendicular to y=(-3/7)x-5, (which is the negative reciprocal of -3/7). So, the new slope is 7/3.
Next, substitute the value of the new slope and the given point (-12,-2) to y=mx+b to find b.
-2=(7/3)(-12)+b
-2=-28+b
b=26
Finally, write the equation of the new line in y=Mx+b format with m=7/3 and b=26.
Answer: y=(7/3)x+26
