Write an equation in slope-intercept form for the line with slope -3/2 and y -intercept -3 how do I make this betterDear Mark Warner,My name is Cody Sprague and, I have emailed you today; I come to you from a school assignment. I'm, asked whether I agree with raising the legal driving age. I agree with this law because; passing a bill to raise the driving age is an effective way to decrease teenage fatalities in traffic accidents. Firstly, teenagers are less likely to wear seatbelts. According to research and statistics show that teenagers are less likely to wear seatbelts. People would argue and say that teenagers are less likely to wear seatbelts, whether driving or not. Teenage drivers spend the mass majority of their time in cars. Secondly, teenage drivers are driving under the influence of alcohol. Research states 70% of teenage drivers who died in underage drinking and driving accidents didn't use a seat belt. Teenagers still can get their hands on alcohol.Lastly, teenage drivers still talk on their phones while driving. Statistics tell us that Talking on a cell phone can double the likelihood of an accident and will slow a young driver's reaction time to that of a 70-year-old.In conclusion, the legal driving age for Virginia; should be raised because for the above reasons. Please consider my reasoning why the driving age should be raised.Many thanks,Cody Sprague I really dont know what to do for this, my teacher didnt really show us how to do it. all she said was "this is your homework assignment and it due Monday" The figure on the left is reflected using the y-axis to form the image on the right.
