Question

How to graph these ?? plzz help
y=999x-3481
y-0.3x=-4
y-x=sin(x)
y=√(16-x^2 )+3
x^2/68+y^2/17=1
x*y=5

Answer 1

first one is a line

Answer 2

second one is \(y=-0.3x-4\) also a line

Answer 3

third one is who knows what some wiggly thing
\[y=x+\sin(x)\]

Answer 4

4th one is a semi circle with radius 4 lifted up 3 units

click on "real valued plot" to get rid of the complex part

Answer 5

thanks <3 @satellite73

Answer 6

Answer 9

not sure how you were supposed to do these, they are very different
kind of weird question
