please help I'm actually crying! Find A and B if the graph of Ax + By = 7 passes through (2,1) and is parallel to the graph of 2x - 7y = 3.

The first four terms of a sequence are shown on the graph below. what can be concluded about the sequence? the common ratio of the sequence is 2. the common difference of the sequence is 2. the next term of the sequence is represented by the point (5, 64). the next term of the sequence is represented by the point (5, –64).
