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

Best ResponseYou've already chosen the best response.1how would you determine the midpoint? match that to the ficticious persons method and see what fits

Best ResponseYou've already chosen the best response.0step two is the midpoint between two point formula and step three is the same but puting in the numbers

Best ResponseYou've already chosen the best response.1Midpoint  endpoint given is the distance and direction to the end point: (MP) add that result to the midpoint to go the same distance and direction further: M+(MP) = 2MP for the other end point

Best ResponseYou've already chosen the best response.1i 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

Best ResponseYou've already chosen the best response.1\[(Mx,My)=\left(\frac{Px+Ex}{2}, \frac{Py+Ey}{2}\right)\] that might seem better

Best ResponseYou've already chosen the best response.1is step 2: x1x2 ? if so then its not the midpt formula

Best ResponseYou've already chosen the best response.1the 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 :)

Best ResponseYou've already chosen the best response.1step 3 is plugging in values and with addition it doesnt matter what goes where since 4+5 = 5+4

Best ResponseYou've already chosen the best response.0okay :) lol thank u wait so if we are doing addition we shouldnt do subtraction right

amistre64

Best ResponseYou've already chosen the best response.1well, if we add, then subtracting is really not a good idea unless you subtract the right value :) 4+5 = 45
