When all the coordinate are plotted on a graph, point (5, 3) and (9, 3) , & point (2, 3) and (7, 3) are found to be in a straight line. So Henry will count some units to find the distance between two points of the coordinate given above.
Step-by-step explanation:by substituting 1 for each of x in the equation. and apply it for problems, if the solution is 0 that means it the solution of x=1
