Do 1-5 write in complete sentences you very much for your time and effort.!

1. B(4,0) and D(8,10)
2. m=rise/run=5/4
y=mx+b
b=0
y=(5/4)x
point (16/20) ,  20=5/4*16,  20=20 true , so point (16/20) is on the line
3.point(20,24) ,  y=(5/4)x,  24=(5/4)*20,  24=25 false,  so point (20,24) is not on the line
4. point(80,100) ,  y=(5/4)x,  100=(5/4)*80,  100=100 true,  so point (80, 100) is  on the line
5. you need substitute values of x and y  into equation y=(5/4)x, if it will be true, then the point is on the line
