the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.
Slope would be undefined because there are many many y-values for one x value. This is impossible for ANY function. To be specific, the correct equation that names the graph is <em>x=4</em>. Please note that this is <u>not</u> a function. If it goes straight up, it is <u>UNDEFINED</u>!!!
Hope I helped!
The answer is <u><em>D</em></u>
4,200+525(5×12)
4,200+525(60)=
4,200+31,500=35,700
