Given that the image of the first-order function y = & frac12; X + 4 intersects the x-axis and y-axis at points a and B respectively, and the edge AC of the trapezoid aobc (o is the origin) is 5, the coordinates of point C are obtained Point a intersects on the X axis, and point B intersects on the Y axis,

Given that the image of the first-order function y = & frac12; X + 4 intersects the x-axis and y-axis at points a and B respectively, and the edge AC of the trapezoid aobc (o is the origin) is 5, the coordinates of point C are obtained Point a intersects on the X axis, and point B intersects on the Y axis,

When y = 0, x = 8, so a (8,0)
When x = 0, y = 4, so B (0,4)
Trapezoidal aobc, so the X coordinate of point C is 8 or the Y coordinate is 4
When the X coordinate of point C is 8, AC = 5, so the Y coordinate of point C is 5; C (8,5)
When the Y coordinate of point C is 4, AC = 5, so 5 ^ 2 = 4 ^ 2 + (8-x) ^ 2, the X coordinate of point C is 5 or 11
