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

or end points or whatever the questions asking ....
