For this problem, in part a, we are asked to find the distance between the points 1 .2, 2 .1, and 3 .1, 2 .4, and 3 .1, 2 .4, and 3 .1, 2 .4, and 3 .1, 2 .1 squared, plus x2 minus x1 squared.
00:23
So we have plus 3 .1 minus 1 .2 squared.
00:28
This will give us that the distance between the two points will be about 1 .9 to 4.
00:33
I'll note that i'm rounding everything to three decimal places.
00:37
For part b, we're asked to find the slope of the line through the two points.
00:42
The slope, which i'll designate m, will be equal to y2 minus y1, 2 .4 minus 2 .1 is going to be 0 .3, divided by x2 minus x1, 3 .1 minus 1 .2...
