Question

Does the equation below represent a lunar relationship? Justify your response. 2x - 5y= -15

Answer 1

Yes, the equation represents a linear relationship.

Explanation:

If you graph it, it is a line.

Also, the exponent on the x and the y is exactly 1. There are no variables in the denominator, nor inside a radical. There are no squared, cubes or higher exponents. All these things will make an equation NOT linear.
