Find the x- and y-intercepts of the graph of the equation. y-9xy+9x=1 x-intercept (x, y) y-intercept (x, y) = Find the x- and y-intercepts of the graph of the equation. y=x+9 x-intercept (x, y) = y-intercept (x, y) = Find the x- and y-intercepts of the graph of the equation. 4x + 25y = 100 x-intercepts (x, y) = (smaller x-value) (x, y) = (larger x-value) y-intercepts (x, y) = (smaller y-value) (x, y) = (larger y-value) Find the center and radius of the circle. x + y = 36 center (x, y) = radius Sketch the graph of the circle.
