Answer:
A. Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis.
Step-by-step explanation:
The rule for a reflection over the x -axis is (x,y)→(x,−y) . The given point is A(-2,1) .The reflected point will be A'( -2,-1) .
To locate the reflected point A' we draw a perpendicular line from A then we measure the distance from point A to x axis along the perpendicular line drawn .The reflected point A' is constructed on the other side which is equidistant from x axis as was point A.
Option A is the right option.
To calculate the amount of molding needed for 10 feet by 7 feet floor, we need to assume some parameters. We can assume that the floor is a regular rectangle with sides 10 and 7 feet. Then the molding needed will be the area of the rectangular floor:
A = l x w
A = 10 feet x 7 feet
A = 70 square feet.
