Unformatted text preview: squares so that they exactly fill the big square in each figure. Guiding Problem #2 Use the following information to draw a graph of a geometric figure. (a) In quadrant 1, the points satisfy the equation y = -3 x + 3. (b) The graph is symmetric with respect to the x-axis, the y-axis, and the origin. List all x-intercepts and all y-intercepts on the graph. What shape did you draw? Follow-up Practice Look at the graphs of y = x 4- 1 x = y 2- 4 x 2 + y 2 = 25 (a) Find the intercepts from the graph and from the equation. (b) Test each equation for symmetry....
