Storyboard Text

  • So if it cost $3.00 to 1 mile and i went 6 miles and that cost $5.25. so if i put those into points it would be (1,3) &(6,5.25). now to find the slope i have to use m=(y2-y1 ) over (x2,x1)
  • Sure no problem hop in and i will take you were you want to go 
  • Hey thanks so much for stoping.
  • how much will it cost to take me to the store  
  • How did you get that
  • I wrote a liner equation
  • That will be $5.25 to go to the store because that is 6 miles away
  • we're here 
  • How much was it for 1 mile?
  • it cost $3.00 to go a mile, ok bye
  • Hey we meet again
  • ?????? I wonder how much it would cost to travel 10 miles to go home
  • So i have to find the slope. mmm, m=5.25-3 over 6-1 which equals .45, so after every mile the cost goes up $.45. now i have to find b, i have to use b=y-mx
  • so b=3-.45(1) mmm, that equals 2.25 so b =2.25. AHA! i have my equation
  • Y=.45x+2.25!!!!
  • Shhhhhhhh!
  • I figured out the cost for 10 miles it would be $7.05. I figured it out by adding 10 to Y=.45(10)+2.25 and that equals 7.05 and that would be $7.05 
  • ok now here is $7.05 now lets go my show is about to come one 
  • wow i'm impressed
