Ellen, a civil engineer, is designing a suspension bridge. There will be a suspnsion cable on each side of the bridge, with support wire hanging down from the cable at different distances, as shown in the table. Using your regression equation, determine the length of a supporting wire that is 48m away from the centre of the bridge. Is this interpolation or extrapolation? Explain

As the name implies, suspension bridges, like the Golden Gate Bridge or Brooklyn Bridge, suspend the roadway by cables, ropes or chains from two tall towers. These towers support the majority of the weight as compression pushes down on the suspension bridge's deck and then travels up the cables, ropes or chains to transfer compression to the towers. The towers then dissipate the compression directly into the earth.
