On Monday Greg walks the entire length of a trail that is 3 1/2 miles long on Tuesday he walks the entire length of a trail that
is 4.6 miles long. On Wednesday he starts out on a trail that is 2 1/5 miles long but he does not walk the final 1.8 miles. How much miles does Greg walk in all on Monday Tuesday and Wednesday
The slope equation is y=mx+b where m is the slope and b is the y intercept. After plugging the numbers into the equation you should get y=-2x+6. Hope this helps!
