1.The equation to the chord joining two points (x1,y1)(x_1, y_1)(x1,y1) and (x2,y2)(x_2, y_2)(x2,y2) on the rectangular hyperbola xy=c2xy = c^2xy=c2 isa.xx1+x2+yy1+y2=1\frac{x}{x_1 + x_2} + \frac{y}{y_1 + y_2} = 1x1+x2x+y1+y2y=1b.xx1−x2+yy1−y2=1\frac{x}{x_1 - x_2} + \frac{y}{y_1 - y_2} = 1x1−x2x+y1−y2y=1c.xy1+y2+yx1+x2=1\frac{x}{y_1 + y_2} + \frac{y}{x_1 + x_2} = 1y1+y2x+x1+x2y=1d.xy1−y2+yx1−x2=1\frac{x}{y_1 - y_2} + \frac{y}{x_1 - x_2} = 1y1−y2x+x1−x2y=1Login to continueOnly logged in users canattempt or see the solution.
