Question

Beck is shown the coordinate grid below with a point plotted on it.

He must plot a second point on the plane using the following:
Start at the plotted point. Subtract 4 from the x-coordinate. Add 5 to the y-coordinate.

Which ordered pair should Beck plot on the grid?

• A. (5,8)
• B. (2,5)
• C. (5,7)
• D. (3,7)

Answer 1

The correct option is C (5,7)


The ordered pair already plotted is (9,2).

Here
x-coordinate = 9
y-coordinate = 2

Subtract 4 from 9 (x-coordinate). Add 5 to 2 (y-coordinate). The new ordered pair that Beck needs to plot is (9 - 4,2 + 5) = (5,7)
