It is known that the image of the first-order function y = 1 / 2 + 4 and the x-axis and y-axis are not called points a and B. the edge AC of the trapezoidal aobc is 5. The coordinate of point C is calculated There seem to be three solutions

y=1/2*x+4?
A(-8,0),B(0,4)
AC is the edge, so AO and BC are the bottom
It's a right angled trapezoid
So there are only two solutions (- 5,4) and (- 11,4)
When you have three solutions, you may take AC as the base, so (- 8,5) is also a solution
