Question

which ordered pair best represents vertex j on the triangle shown above? a (7,9) b (9,6) c (6,9) d (9,7)

Explanation:

Step1: Recall ordered pair format

An ordered pair is \((x, y)\), where \(x\) is the horizontal (x - axis) coordinate and \(y\) is the vertical (y - axis) coordinate.

Step2: Find x - coordinate of J

Looking at the graph, vertex J is above the x - value of 6 on the x - axis. So the x - coordinate of J is 6.

Step3: Find y - coordinate of J

Looking at the graph, vertex J is at the y - value of 9 on the y - axis. So the y - coordinate of J is 9.

Step4: Form the ordered pair

Combining the x and y coordinates, the ordered pair for J is \((6, 9)\), which matches option C.

Answer:

C. (6,9)
