You can start with the form
∆y(x -x1) -∆x(y -y1) = 0
Here, we have
∆y = 11-(-3) = 14
∆x = -3-1 = -4
and we can choose (x1, y1) = (1, -3). This gives
14(x -1) -(-4)(y -(-3)) = 0
14x +4y -2 = 0
All these terms have a common factor of 2 that we can remove. Adding 1 to the result puts it in standard form:
7x +2y = 1
Answer: you just multiply the big by the percentage. But change the percentage to a decimal. There only two operating when dealing with percentage. Add or subtract. Once you multiply the percentage with big number add or subtract the answers with the big number.
