Hi,
what is the distance between
(-5,-3) and
(4,-7) Distance = sqrt%28%28-9%29%5E2+%2B4%5E2++%29=+sqrt%2897%29
D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29
Midpoint Pt(x,y): ( %28x%5B1%5D+%2B+x%5B2%5D%29%2F2, %28y%5B1%5D+%2B+y%5B2%5D%29%2F2++%29)
Slope of line passing thru these two points: m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
point-slope form the line passing thru these two points: y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29
