lizxy place 5 tiles at first at day 1, at the end of day 4, she had placed 35 tiles. she worked on a steady rate. use a equation in point slope form to determind how many days she need for 100 tiles to finish
point slope form is (y−y0)=m(x−x0)In this case (x0,y0)=(1,5)Now to find m we use m=y1−y0x1−x0 where (x1,y1) is any other point known to be on the line.In this case (x1,y1)=(4,35) and we compute m asm=35−54−1=303=10So our final equation is (y−5)=10(x−1)
