What are the lines of best fit for each of these individual tables. please help me guys i just dont have the calculator to solve this yet!! please!

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Plzzz i beg u so much asaaaap ! what is the slope of this line? enter your answer in the box.

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.
