Which point is on the line y=-2+3? (-2,-1) (3,3) (3,-3) (-3,-9)

What are the coordinates of the midpoint of ab? ,1/2) /2,-1) ,-3/2) /2,-2)

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39
