Suppose you want to make a square using the graph of 3-2y=-30 to help determine on side of the square . Write equations in standard form to determine a square with cornes at (－8,3), (-14,7), (-10, 13) and (-4,9).

Question

Suppose you want to make a square using the graph of 3-2y=-30 to help determine on side of the square . Write equations in standard form to determine a square with cornes at (－8,3), (-14,7), (-10, 13) and (-4,9).

Answer 1

Since one line is 3x-2y = -30

any other lines will have to be of the form 2x+3y = k
to make (-8,3) lie on both lines, k = -7

Now you can use the other points to determine the constants for the other lines.
