My assumption is that you'd graph this as a horizontal line at (0,-2) but PLEASE double check with your teacher/instructor because I'm not sure if I'm right.
You'll need to share the graphs mentioned in this problem statement.
One can solve 2y + 4 = 0 for y and thus obtain an equation which is easy to graph:
2y + 4 = 0 becomes
2y = -4, or
y = -2
The graph of this function is the horizontal line y = -2. Find (0, -2) on your set of coordinate axes and plot a dark dot there. Then draw a horizontal line thru it. This line has a slope of zero (0) and a y-intercept of -2.
It has two congruent angles because if they do have two congruent angles, then they are called and isosceles triangle. Hope this helps and if it did, please mark as brainliest.
