Write the equation of a line that is perpendicular to the given line and that passes through the given point. β3x β 6y = 17; (6, 3) y = x β 9 y = 2x β 9 y = β2x β 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 β 5 = (x β 1). the relationship is not linear. the relationship is linear; y β 5 = (x β 1). the relationship is linear; y β 1 = (x β 5). write an equation in point-slope form for the line through the given point with the given slope. (β10, β1); m = y + 10 = (x + 1) y β 1 = (x β 10) y β 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 | β 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x β 5.5 | y = | x | β 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | β 8 y = | x | + 8 y = | x β 8| y = | x + 8|

Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). suppose your car averages 33 miles per gallon on the highway if your average speed is 54 miles per hour, and it averages 22 miles per gallon on the highway if your average speed is 75 miles per hour. answer parts (a) and (b) below. a. what is the driving time for a 2000-mile trip if you drive at an average speed of 54 miles per hour? what is the driving time at 75 miles per hour? the driving time at 54 miles per hour is nothing hours. (type an integer or decimal rounded to two decimal places as needed.) the driving time is at 75 miles per hour is nothing hours. (round to two decimal places as needed.) b. assume a gasoline price of $3.33 per gallon. what is the gasoline cost for a 2000-mile trip if you drive at an average speed of 54 miles per hour? what is the gasoline cost at 75 miles per hour? the gasoline cost at 54 miles per hour is $ nothing. (round to two decimal places as needed.) the gasoline cost at 75 miles per hour is $ nothing. (round to two decimal places as needed.)
