An equation for a line in the xy-plane allows you to find the value of y, given x

This statement is true. A linear equation has two variables, x and y, it is commonly written as an equation y in express in terms of x. The variable y is the dependent variable while x is the independent variable. If you have a value of x and substitute it to the equation, you would be able to find the value of y.

Iwould like to think so. what’s the question you need with?

That. you would have multiple
