We know that distance = rate(time). We need to solve for time here.

The car took 2 hours to travel 90 miles at a speed of 45 mi/hr
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
To find corresponding angles and sides, you look at the name of the figure and see which one correlates.
