Question

Which equation contai262 Which equation contains the points (1, 5) and (-1, 5)? Ax^2 + y^2 = 5

By = 2x + 3 Cy = x^3 + 4 Dy = x^2 + 4

Answer 1

There are many to choose from, but a simple one would be
`y = 5`, since both points contain a y-value of 5. Remember that
`y = 5` is the same thing as
`0x + y = 5`, in case it causes confusion due to the absence of an
`x` variable.

Some more equations which would satisfy these points:

• 
  `5|x| = y`
• 
  `y = 5x^2`
• 
  `y = \cos(2\pi x) + 4`
