If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after 2 hours of driving after her coffee break, her distance from her house was 210 miles. her average speed during the whole trip was 60 miles per hour.valerie created the equation y−210=60(x−2) to represent this situation, where xx represents the time in hours from her coffee break and yy represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
