I’m the previous problem, you wrote equations that were models of real-life situation. Models are usually not perfect representations, but they are useful for describing real-life behavior and for making predictions you predicted when the two trees would be the same height

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)
