In Maple Heights, Ohio, there was 15 inches of snow on the ground in January. Then snow fell during a snow storm at a rate or 2.5 inches per hour. The local meteorologist created a linear model to relate the number of inches of snow on the ground, y, and the number of hours since the snow storm began, x.
Which answer choice correctly interprets the slope and yintercept of this linear model? A.) The slope is 15 inches and the yintercept is 2.5 inches. B.) The slope is 37.5 inches and the yintercept is 2.5 inches. C.) The slope is 2.5 inches and the yintercept is 15 inches. D.) The slope is 2.5 inches and the yintercept is 37.5 inches.
The starting amount was 15 inches {that is when the time is zero or the yintercept}
The rate of the snow falling is 2.5 inches per hour {that is the rate of change or the slope} Answer is C.) The slope is 2.5 and the yintercept is 15 inches. Ask Algebra House
