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:

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