I find it simplest to convert to standard form, find the perpendicular, convert back.
For standard form we move the x term to the left side:
The perpendiculars are given by swapping the x and y coefficients, negating one. The right side is directly determined by the point (-2,7):
Solve for y for point slope form:
That's the answer.

The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
