5. Write a slopeintercept equation for a line passing through the given point that is parallel to the given line. Then write a second equation for a line passing through the given point that is perpendicular to the given line. (5, 0), y= o.9x+4.7 Choose the correct equations. 0 A. _ 1o 50 parallel: y = - 0.9x + 4.5 perpendicular: y = ?x - ? O B. _ 1o 50 parallel: y = - 0.9x - 4.5 perpendicular: y = ?x + ? O c. 10 50 parallel: y = 0.9x - 4.5 perpendicular: y = - x - 9 9 6. The chart shows the cost of tuition at a certain state College Year, x university. Model the data in the chart with a linear function, using the points (1, 9997) and (311308). Predict the cost of 1997 _1998' 0 college tuition in 20042005. 1998 ' 1999- 1 1999 2000, 2 2000 - 2001, 3 2001 2002, 4 What is the linear model for the data? y = Estimated Tuition, y $9493 $ 9997 $10622 $1 1308 $12026 (Type your answer in slope-intercept form. Use integers or decimals for any numbers in the expression. Round to the nearest tenth as needed.) What will college tuition cost in 2004 - 2005? $ (Round to the nearest dollar.)
