Step-by-step Solution
1. Identify the given slope: The slope of the given line y = 11x - 5 is 11.
2. Find the negative reciprocal: The negative reciprocal of 11 is .
3. Determine the intersection point: Substitute y = 17 into the given equation to find the corresponding x-coordinate:
17 = 11x - 5
22 = 11x
x = 2
So, the intersection point is (2, 17).
4. Use the point-slope form: Substitute the point (2, 17) and the slope into the point-slope form :
