2/3x-5/4y=7 solve in standard form

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.
