So for this problem, we're asked to figure out if t is going to lie on the perpendicular bisector.
00:07
It says of line np, but i think it meant line segment.
00:11
And i put the points on here.
00:13
Now, the first thing you have to find is the midpoint of what i would think would be line segment np.
00:20
So i'm going to use the formula x1 plus x2 over 2, comma, y1 plus y2 over 2.
00:34
So then i'm going to plug in the points for n, 1, 1, and then for p, i'm going to plug in 5 and 7.
00:51
So that would give me 6 over 2, which is 3, and 8 over 2, which is 4...
