A vertical line in the xy coordinate plane would represent the line of an equation such as x = 1 or x = -4.
A linear equation.

A linear equation.
To work out the equation of a straight line the slope and an (x, y) coordinate must be given
True. -
"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3
All points whose y-coordinate is twice its x-coordinate.

A straight line.
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
An equation with an undefined slope is typically in the form x = a, where 'a' is a constant number. This indicates a vertical line on the coordinate plane, where every point on the line has the same x-coordinate and no defined slope because the line is perfectly vertical.
It is the locus of all points whose coordinates satisfy the equation of the line.
