OK im in the ALGEBRA 1 McDougal Littel book and im on lesson 4.6 ; on page 246 theres a problem #66 and i dont understand it at all!! the first information says:
"You are supervising the construction of a roller coaster for young children. For the first 20 feet of horizontal distance, the track must rise off the ground at a constant rate. After your crew has constructed 5 feet of horizontal distance, the track is 1 foot off the ground."
the problem #66 says:
"Plot points for the heights pf the track at 5-foot intervals. Draw a line through the points. Find the slope of the line. What does the slope represent?"
i understand slope intersept from y=mx +b. but i dont know how to get a starting equation! can someone help???
