A construction crew is lengthening a road that originally measured 44 miles. The crew is adding one mile to the road each day. Let L be the length (in miles) after D days of construction. Write an equation relating L to D . Then use this equation to find the length of the road after 35 days.
Ok so on day 0 we know the road was 44 miles, thats our intercept. Now if only 1 mile is added per day, then we get [tex]l = d + 44[/tex] Now lets plug in 35 [tex]l = 35 + 44 \\ l = 79[/tex] After 35 days the length of the road was 79 miles.
