The New Horizons space probe was launched on January 19, 2006. Assume that New Horizons travels in a straight line, perpendicular to the launch site. An equation used to model the relationship between the distance, y, in miles, from Earth to New Horizons and the number of hours since being launched, x, is y=32,500x. Part A What is the meaning of the slope of the line defined by this equation? A New Horizons travels 32,500 hours after its launch. B New Horizons travels 32,500 miles per hour. C New Horizons travels 32,500 miles every day. D New Horizons travels 32,500 miles from Earth. Part B What is the distance, in miles, from Earth to New Horizons 2.5 hours after it is launched? The distance from Earth to New Horizons is miles.

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
