37+z≤54
. graph the solution.

See attached picture.

Step-by-step explanation:

Solve the inequality:

Graph the solution by placing a closed dot (or filled in dot) on 17 on the number line. This is closed or filled in since z is less than or equal to. Then for the less than part, shade to the left of 17.

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.
