How are solutions, roots, x​ -intercepts, and zeros related?

• The solutions are the y​ -values that correspond to the roots, x​ -intercepts, and zeros of an equation.

• The solutions are the roots, and are the y​ -values that correspond to the  x​ -intercepts and the zeros of an equation.

• There are two roots or zeros for every  x​ -intercept or solution of an equation.

• The solutions are the same as the roots of the equation and are the same as the x​ -intercepts or zeros of the related equation.
