One of the endpoints of the base of a triangle is at P(4, 5). The midpoint of the base is at (1, 1). Erik performed the steps shown to find the coordinates of the other endpoint of the base. Step 1. x1 = 4, y1 = 5, x = 1, y = 1 Step 2. Step 3. Step 4. 2 = 4 + x2, 2 = 5 + y2 Step 5. 0 = 4 + x2 , 0 = 5 + y2 Step 6. x2 = -4, y2 = -5 In which step did Erik first make an error? Answer Step 2, because he used the formula to find the length of a line segment. Step 3, because he substituted the values incorrectly in the formula Step 4, because he multiplied both the equat

does step 4 pr 5 look wronf i cant figure out how t owrite out step 2 and 3

how would you determine the midpoint? match that to the ficticious persons method and see what fits
amistre64
  • amistre64
or end points or whatever the questions asking ....

step two is the midpoint between two point formula and step three is the same but puting in the numbers
amistre64
  • amistre64
Midpoint - endpoint given is the distance and direction to the end point: (M-P) add that result to the midpoint to go the same distance and direction further: M+(M-P) = 2M-P for the other end point

so step 4 would be wrong?
amistre64
  • amistre64
2M = (2 , 2) - P = (-4,-5) ------------- (-2,-3) is what I get
anonymous
  • anonymous
okay but i have to find out what step is wrong thats what i dont get
amistre64
  • amistre64
i dont do the ficticious persons steps, so I really cant say wear they messed up at .... and it would help to know what step 2 and 3 actually were
amistre64
  • amistre64
maybe a formula?
amistre64
  • amistre64
\[\left(\frac{Mx-Px}{2}, \frac{My-Py}{2}\right)\]
amistre64
  • amistre64
that doesnt quite jive ....
amistre64
  • amistre64
\[(Mx,My)=\left(\frac{Px+Ex}{2}, \frac{Py+Ey}{2}\right)\] that might seem better
amistre64
  • amistre64
M for midpt, P for given Point, and E for other endpt

i hope u understand that lol i tried
amistre64
  • amistre64
is step 2: x1-x2 ? if so then its not the midpt formula
anonymous
  • anonymous
no it x1 plus x2
amistre64
  • amistre64
the midpt is an average of 2 points; an average is sum up the points and divide by ...well 2 since htere are only 2 points :)
amistre64
  • amistre64
then step 2 looks fine if its addition
anonymous
  • anonymous
okay so its 3 4 or 5 lol i hate this thank u for workn with me ot figure it out
amistre64
  • amistre64
step 3 is plugging in values and with addition it doesnt matter what goes where since 4+5 = 5+4
anonymous
  • anonymous
okay sooo three is wrong im confused
amistre64
  • amistre64
3 is fine
amistre64
  • amistre64
4 is fine, sicne 2*1 = 2 in both accounts
amistre64
  • amistre64
there is no reason for making step 5 zero out
anonymous
  • anonymous
okay :) lol thank u wait so if we are doing addition we shouldnt do subtraction right
amistre64
  • amistre64
well, if we add, then subtracting is really not a good idea unless you subtract the right value :) 4+5 = 4--5
amistre64
  • amistre64
rides here, good luck :)
amistre64
  • amistre64
my bet is step 5 tho

  • anonymous
thank u soo much
