Question

an equation for a line in the plane allows you to find x- and y-coordinates of any point on that line true or false?

Answer 1

True.

Explanation:

An equation for a line in the plane allows you to find x- and y-coordinates of any point on that line.

Answer 2

True

Explanation:

When you are given an equation of a line in the plane, it´s like if they´ve given you the map to a line, and in this case it´s really easy to calculate the value of the different points on X and Y and by that you just have to immagine a value for one of the variables to calculate the other one, most cases is always X the one that you give the value to, and then you just calculate the Y.
