Find the midpoint of the segment with endpoints (-4,5) (1,3) and enter its coordinates as an ordered pair. Please help

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

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
