Find the line of best fit for the set of data: x y -2 2.9 -3.5 2 1.4 4.8 -4.2 1.5 0 4 2.8 6 -1.5 3.5 y = .613x + 4.142 y = .613x - 4.142 y = -.613x - 4.142 y = -.613x + 4.142

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

its 8

step-by-step explanation:

the two may have that, even a breakdown is probably offered

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
