A- Perpendicular lines have negative reciprocal slopes. Therefore a perpendicular line to 2x-8 will have a slope of -1/2. Once solved in slope intercept form, choice A shows a line of slope -2/4, equivalent to -1/2
As a percentage it would be 63.5% and as a fraction it would be 635/ 1000 or 127/200
