Cassidy’s family is driving home from vacation at an average speed of 55 mph. after 2 hours they are 110 miles from home. what is an equation in point-slope form that represents their distance y from home, after x hours. a. y − 110 = −55(x − 2) b. y − 55 = 110(x − 2) c. y − 2 = 55(x − 110) d. y − 110 = 55(x − 2)

D.

Step-by-step explanation:

Cassidy’s family is driving home from vacation at an average speed of 55 mph.

Initially, at x = 0 hours, the family is y = 0 miles away form home. We get the first point (0,0).

After x = 2 hours, the family is y = 110 miles from home. We get the second point (2,110).

The equation in point-slope form that represents their distance y from home, after x hours is
