Select all statements that are true about the linear equation. y = - x - 1

a.) The point (0, - 1) lies on the graph of the equation.
b.) A coordinate pair on the graph of the equation is a solution to the equation.
c.) The graph of the equation is the set of points that are solutions to the equation.
d.) The point (1, 2) lies on the graph of the equation.

greater than one

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
