Triangle abc has vertices a(5, 3) , b(3, 7) , and c(1, 4) . triangle abc is dilated, and the vertices of the image are a′(1.25, 0.75) , b′(0.75, 1.75) , and c′(0.25, 1) . the center of dilation is the origin. what is the scale factor of the dilation? a. 0.25 b. 0.5 c. 2 d. 4

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

Classify the following triangle check all that apply
