Review some of your classmates' posts and respond to at least two of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies early during the week to promote more meaningful interactive discourse in the discussion. Each response to your peers should be at least 150 words. Make your replies meaningfulfind an error, expand a problem, ask a question, and resolve the problem or part of the problem to verify their solution. Hello Class, My assigned number is 7. The first question is as follows. Find the slope of a line connecting the points (1, 6) and (2, 18). To find the slope of the line connecting the points (-1,6) and (2,18), we should use the formula m= y2 - y2/x2 - x1. This will then look like m=18-6/2-(-1). Which will solve down to 12/3, which will then equal 4. So our slope is 4, or m=4. The second question is. A car begins a trip at t = 0 hours and travels 90 miles and stops at t = 5 hours. What is the average speed? To solve this equation we simply need to put the average speed over the average time, which will be 90 miles/5 hours. When divided we get an average speed of 18 miles per hour. My topic is travel. Imagine you're planning a road trip and you want to know how far you can travel in one day, in this situation we can use a linear equation to calculate our distance traveled. Let's use the equation d=rt, where d = distance traveled, r= average speed (in mph) and t=time elapsed (in hours). To solve this equation you can input
