Answer:
Yes, it is a function
Step-by-step explanation:
-2x+4y=0 is a function as it maps one x value to just one y value.
-2x+4y=0 can be rearranged to turn it into a linear equation:
-2x+4y=0
4y=2x
y=x/2
Since this equation is a line (see in attatched graph) and every x value has just one y value, it is a functuon.
