There are many to choose from, but a simple one would be [tex]y = 5[/tex], since both points contain a y-value of 5. Remember that [tex]y = 5[/tex] is the same thing as [tex]0x + y = 5[/tex], in case it causes confusion due to the absence of an [tex]x[/tex] variable.
Some more equations which would satisfy these points:
- [tex]5|x| = y[/tex]
- [tex]y = 5x^2[/tex]
- [tex]y = \cos(2\pi x) + 4[/tex]
